Here's how to easily find the right size."},"content":{"rendered":"<p class=\"wp-block-paragraph\">You're probably familiar with this: a hydraulic cylinder starts leaking, you take it apart and discover that a seal is worn out. You know roughly what size you need, but a part number is missing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">And then the search begins\u2026<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At HydrauliekService in Beesd, we regularly have customers looking for a seal but who don't know exactly which type they need. That's why we have a handy <strong>online seal finder<\/strong> developed. With this, you can easily search for hydraulic seals, oil seals, and O-rings by size, type, and material.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In this blog, we explain how to measure a seal and how to find the right part with our finder.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">1. How do you measure a hydraulic seal?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">To find the correct seal, the dimensions are important. Preferably use a caliper and, if possible, also check the dimensions of the installation space.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For many hydraulic seals, we look at three dimensions:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Size 1:<\/strong> usually the smaller diameter, for example the inner diameter.<\/li>\n\n\n\n<li><strong>Size 2:<\/strong> usually the larger diameter, for example the outer diameter of the seal.<\/li>\n\n\n\n<li><strong>Height or room size:<\/strong> the available width of the sealing groove.<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">The exact size that applies depends on the type of seal.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img fetchpriority=\"high\" decoding=\"async\" width=\"1024\" height=\"683\" src=\"https:\/\/hydrauliekservice.nl\/wp-content\/uploads\/2026\/11\/Digitale-schuifmaat-meet-oliekeerring-1024x683.webp\" alt=\"\" class=\"wp-image-209212\" srcset=\"https:\/\/hydrauliekservice.nl\/wp-content\/uploads\/2026\/11\/Digitale-schuifmaat-meet-oliekeerring-1024x683.webp 1024w, https:\/\/hydrauliekservice.nl\/wp-content\/uploads\/2026\/11\/Digitale-schuifmaat-meet-oliekeerring-300x200.webp 300w, https:\/\/hydrauliekservice.nl\/wp-content\/uploads\/2026\/11\/Digitale-schuifmaat-meet-oliekeerring-768x512.webp 768w, https:\/\/hydrauliekservice.nl\/wp-content\/uploads\/2026\/11\/Digitale-schuifmaat-meet-oliekeerring-18x12.webp 18w, https:\/\/hydrauliekservice.nl\/wp-content\/uploads\/2026\/11\/Digitale-schuifmaat-meet-oliekeerring-500x333.webp 500w, https:\/\/hydrauliekservice.nl\/wp-content\/uploads\/2026\/11\/Digitale-schuifmaat-meet-oliekeerring-600x400.webp 600w, https:\/\/hydrauliekservice.nl\/wp-content\/uploads\/2026\/11\/Digitale-schuifmaat-meet-oliekeerring-64x43.webp 64w, https:\/\/hydrauliekservice.nl\/wp-content\/uploads\/2026\/11\/Digitale-schuifmaat-meet-oliekeerring.webp 1536w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>An example:<\/strong> You are looking for a rod seal for a 40 mm rod with an outer diameter of 50 mm. Then you can start searching for 40 \u00d7 50 mm.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Please note: dimensions alone are not always sufficient. The profile, material, and application must also match.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Important: the room size is not always the actual height<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">At HydrauliekService, many seals are specified by chamber size. This means that the stated height of the installation space is often approximately 1 mm greater than the actual height of the seal.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Take this into account when measuring or replacing a seal. Also, always check the specifications of the chosen profile.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">2. Not every seal is the same<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">There are many different types of seals. A few common examples are:<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Rod seals<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These ensure that hydraulic oil does not leak out along the moving piston rod.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Piston seals<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These ensure the seal between the piston and the cylinder tube, so that hydraulic pressure can be built up properly.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Scrapers<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These remove dirt, dust, and moisture from the moving piston rod, thereby helping to protect the seals in the cylinder.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>O-rings<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These are used, among other things, for static seals in hydraulic systems. Depending on the application, they can also be part of a dynamic sealing structure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Oil seals<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">These are often used in rotating shafts, for example in pumps, motors, and drives.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">It is therefore important not only to look at the dimensions, but also at the function of the seal.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">3. Search easily with our online seal finder<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Because searching through thousands of different sizes can be quite time-consuming, we at HydrauliekService have developed our own search function.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This allows you to search specifically without having to know an article number first.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Here's how it works:<\/strong><\/p>\n\n\n\n<ol start=\"1\" class=\"wp-block-list\">\n<li>Open our <a href=\"https:\/\/hydrauliekservice.nl\/product-categorie\/afdichtingen\/\"><span style=\"color: var(--theme-palette-color-1, #120CBF);\" class=\"stk-highlight\"><strong>online seal finder<\/strong><\/span><\/a>.<\/li>\n\n\n\n<li>Optionally select the main group, the type of seal, the series, or the material.<\/li>\n\n\n\n<li>Enter the measurements you know.<\/li>\n\n\n\n<li>Click on \u2018Search\u2019 and view the results.<\/li>\n\n\n\n<li>Compare the found articles and choose the seal that suits your application.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">You don't have to fill in all the details. For example, do you only know that you need a 40 \u00d7 50 mm seal? Then you can start with that.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">You can also search within a size range. This is handy when you are not entirely sure about a size or want to compare multiple measurements.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"587\" src=\"https:\/\/hydrauliekservice.nl\/wp-content\/uploads\/2026\/11\/Afidchtingen-zoeken-1024x587.jpg\" alt=\"\" class=\"wp-image-209213\" srcset=\"https:\/\/hydrauliekservice.nl\/wp-content\/uploads\/2026\/11\/Afidchtingen-zoeken-1024x587.jpg 1024w, https:\/\/hydrauliekservice.nl\/wp-content\/uploads\/2026\/11\/Afidchtingen-zoeken-300x172.jpg 300w, https:\/\/hydrauliekservice.nl\/wp-content\/uploads\/2026\/11\/Afidchtingen-zoeken-768x441.jpg 768w, https:\/\/hydrauliekservice.nl\/wp-content\/uploads\/2026\/11\/Afidchtingen-zoeken-18x10.jpg 18w, https:\/\/hydrauliekservice.nl\/wp-content\/uploads\/2026\/11\/Afidchtingen-zoeken-500x287.jpg 500w, https:\/\/hydrauliekservice.nl\/wp-content\/uploads\/2026\/11\/Afidchtingen-zoeken-600x344.jpg 600w, https:\/\/hydrauliekservice.nl\/wp-content\/uploads\/2026\/11\/Afidchtingen-zoeken-64x37.jpg 64w, https:\/\/hydrauliekservice.nl\/wp-content\/uploads\/2026\/11\/Afidchtingen-zoeken.jpg 1304w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">4. You can also easily search for O-rings.<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">In addition to hydraulic seals, our finder features a separate function for O-rings.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For an O-ring, the inner diameter and the cord thickness are particularly important.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For example, do you have an O-ring with an inner diameter of 15.88 mm and a cord thickness of 2.62 mm? Then you can search specifically for these dimensions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When it comes to O-rings, also pay attention to the material and application. Not every O-ring is suitable for the same oil, temperature, or operating pressure.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"593\" src=\"https:\/\/hydrauliekservice.nl\/wp-content\/uploads\/2026\/11\/O-ringen-zoeken-1024x593.jpg\" alt=\"\" class=\"wp-image-209215\" srcset=\"https:\/\/hydrauliekservice.nl\/wp-content\/uploads\/2026\/11\/O-ringen-zoeken-1024x593.jpg 1024w, https:\/\/hydrauliekservice.nl\/wp-content\/uploads\/2026\/11\/O-ringen-zoeken-300x174.jpg 300w, https:\/\/hydrauliekservice.nl\/wp-content\/uploads\/2026\/11\/O-ringen-zoeken-768x445.jpg 768w, https:\/\/hydrauliekservice.nl\/wp-content\/uploads\/2026\/11\/O-ringen-zoeken-18x10.jpg 18w, https:\/\/hydrauliekservice.nl\/wp-content\/uploads\/2026\/11\/O-ringen-zoeken-500x290.jpg 500w, https:\/\/hydrauliekservice.nl\/wp-content\/uploads\/2026\/11\/O-ringen-zoeken-600x347.jpg 600w, https:\/\/hydrauliekservice.nl\/wp-content\/uploads\/2026\/11\/O-ringen-zoeken-64x37.jpg 64w, https:\/\/hydrauliekservice.nl\/wp-content\/uploads\/2026\/11\/O-ringen-zoeken.jpg 1302w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">5.

We know from experience how difficult it can sometimes be to find exactly the right part.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Especially when you have an old, worn seal whose article number is no longer legible.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That is why we wanted to make searching easier. No endlessly scrolling through product lists, but simply being able to search using the data you do have.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Our seal finder is available immediately via the webshop and works on both a computer and a smartphone.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This way, you can also easily search for the right parts in the workshop.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">6. Still not sure which seal you need?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">No problem. A seal may appear exactly the same at first glance, while there are still differences in profile, material, or application.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Are you unsure? Feel free to send us a photo of the old seal, along with the dimensions and information about the application.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Or visit HydrauliekService in Beesd. We are happy to think along with you.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">With our extensive range and years of practical experience, we help you find the right solution.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Looking for a hydraulic seal yourself?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Try our online search tool and discover how simple it can be.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a href=\"https:\/\/hydrauliekservice.nl\/product-categorie\/afdichtingen\/\"><span style=\"color: var(--theme-palette-color-1, #120CBF);\" class=\"stk-highlight\"><strong>View the seal finder and search directly by size.<\/strong><\/span><\/a><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>HydrauliekService BV \u2013 Beesd<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><em>The best advice is to have stock!<\/em><\/p>","protected":false},"excerpt":{"rendered":"<p>Je kent het vast wel: een hydraulische cilinder begint te lekken, je haalt hem uit elkaar en ontdekt dat een afdichting versleten is.
