Rubber Seals & O-Rings
O-Rings
O-rings in nitrile, EPDM, silicone and other compounds, supplied for hydraulic systems where they prevent fluid leakage between connected parts, pneumatic systems where they seal air and prevent pressure loss, and water filtration systems where they stop contaminants bypassing the filter. The simple design means installation is quick, and the cost per seal is low relative to the failure it prevents.

Product Overview
O-rings in nitrile, EPDM, silicone and other compounds, supplied for hydraulic systems where they prevent fluid leakage between connected parts, pneumatic systems where they seal air and prevent pressure loss, and water filtration systems where they stop contaminants bypassing the filter. The simple design means installation is quick, and the cost per seal is low relative to the failure it prevents.
Key Benefits
- One seal type covers hydraulic, pneumatic and filtration duties
- Compound chosen by fluid and temperature rather than by what is in stock
- Simple design gives quick installation with no special tooling
- Low cost relative to the consequence of a leak
- Standard and custom sizes both available
Problems It Solves
- Seals failing early because the compound does not suit the fluid
- Leaks at connections that are difficult to access and repair
- Pressure loss in pneumatic systems from poor sealing
- Filtration bypass that lets contaminants through
Where It Is Used
Applications And Buyers
Application Scenarios
- Preventing fluid leakage between connected parts in hydraulic systems

Compared With The Alternatives
| Y seals | O-rings are the right answer for static seals and light dynamic duty; Y profile lip seals take over in reciprocating hydraulic cylinders. |
|---|---|
| Flat gaskets | An O-ring seals in a controlled groove with a predictable squeeze; a flat gasket depends on bolt load across the whole face. |
Use Guide
- Choose the compound from the fluid first, then check the temperature range
- Machine the groove to the recommended dimensions, since squeeze decides sealing
- Check the surface finish of both sealing faces
- Avoid stretching the O-ring over sharp edges during installation
Questions
Questions Buyers Ask About This Product
Which compounds do you supply?
Nitrile, EPDM, silicone and other compounds depending on the fluid and temperature.
Can you make non standard sizes?
Yes. Send the groove dimensions or the required inside diameter and cross section.
Which compound suits water systems?
EPDM performs well in water and steam. Nitrile is the usual choice for mineral oils and fuels.
Are O-rings suitable for pneumatic systems?
Yes, they seal air and prevent loss of pressure, which is one of their main applications.
Is there a minimum order quantity?
Quantities are quoted per size and compound. Send your requirement and we will confirm.
