Hydraulic Equipment Manufacturing and Repair Sealing Supply

Cylinder repair margins depend on getting the right seal the first time. The usual obstacles are:

• Unknown cylinder makes with no available seal kit data
• Worn grooves and rods that make measurement unclear
• A wide spread of profiles, from simple U-cups to multi-piece piston assemblies
• Contamination, side loading and misalignment that cause repeat failures
• Customers waiting while parts are identified

These product families are commonly enquired about in this sector. Open any page for sizes, materials and buying options.

• Rod seals: Rod seals in several profiles and materials.
• Piston seals: Piston seals, single and double acting.
• Wiper and scraper seals: Wipers and scrapers to protect rod seals.
• Wear rings and guide rings: Wear rings and guide rings.
• Backup rings: Backup rings for O-ring grooves under pressure.

You can also browse all product categories or the online shop, where products are being added.

Seal profile and compound depend on pressure, speed, temperature, fluid and cylinder type. Polyurethane is typically common in rod and piston seals, with PTFE-based profiles for lower friction and higher speed, but every profile has its own limits. These are general notes; check against the manufacturer's data for your application.

Information that speeds up a correct recommendation:

• Rod diameter, bore diameter and groove width and depth
• Working pressure, speed and stroke
• Hydraulic fluid type and temperature
• Cylinder make and model, and whether the seal is single or double acting

Our hydraulic cylinder sealing support service covers what to send and how we review it. A photo of the removed seals laid out in order, with measurements, gives the best chance of a quick answer.

If you are unsure what you have, start with find my seal, upload a drawing, or read about our technical support.
