COMPATIBILITY & APPLICATIONS
Common Uses
Compatible with reverse osmosis housings, filter canisters, and general plumbing connections where standard 5/8" ID seals are required. Buna-N material offers good resistance to water, petroleum oils, and mild chemicals, making these O-rings suitable for residential and light commercial water treatment equipment. The 70A durometer provides a balance between flexibility and compression resistance for reliable sealing without deformation under typical operating pressures.
💧 Store unused O-rings in a cool, dark location away from ozone sources to prevent premature aging of the nitrile rubber compound.
