Fluorine Rubber O-Rings 19 mm OD

These 20-piece fluorine rubber O-rings suit maintenance technicians and DIY repairers who need reliable seals for pumps, filters, pressure washers and general plumbing. The 70A durometer material resists penetration while maintaining flexibility across demanding service conditions.

Working pressure limited to 0.3 bar

The seals are rated for a maximum working pressure of 0.3 bar, so they suit low-pressure hydraulic, pneumatic and water circuits but not high-pressure power-steering or injection systems. Temperature tolerance spans -30 °C to 280 °C (-22 °F to 536 °F), covering most automotive and industrial fluid environments.

19 mm outer diameter, 16 mm inner diameter.

These three dimensions determine whether the ring fits your groove; verify them against the component before ordering. The pack contains 20 identical brown FKM rings with broad resistance to mineral oils, greases, fuels, HFD fluids and many organic solvents.
