What are hydraulic seals and what are hydraulic seals used for?

A hydraulic seal is a soft ring that sits in a groove or is fixed in a combination of rings, forming a seal assembly that works to prevent or separate fluid in reciprocating motion applications. Hydraulic seals are crucial in machinery. At Monomer, we have been supplying into the hydraulic aftermarket for over 20 years under the MR Quality Parts brand. We have supplied hydraulic cylinder seals to: construction specialists, refurbishment and repair companies, dealers and distributors within the UK and across the world.

Our hydraulic seal kits are manufactured as alternatives to OEM parts, which include: a wiper seal, u-seals, composite seals, o-rings, back-up rings, a quad ring and special-style seals.

What causes hydraulic seals to fail?

Hydraulic cylinder seals are very robust and long-lasting when used in the correct application settings. However, when used in the wrong setting, hydraulic seals can cause serious problems. The main reasons as to why hydraulic seals can fail include:

  • Improper installation

  • Heat erosion

  • Contamination

  • Chemical erosion

  • Types of hydraulic seals available at Monomer
