GASKET, 60 DURO BUNA-N, 3.000" 300# FF

A flange gasket fills the microscopic imperfections in flange faces so the joint holds pressure. Supplementary detail from the product record: NPS, 0.125 THK.

Expect good resistance to propane and butane, hydraulic fluids, and water. Buna-N (Nitrile) is widely chosen for low compression set under sustained load and the most widely specified general-purpose sealing elastomer. Applications involving ketones or ozone and direct sunlight call for a different compound.

You will find this material specified across agricultural equipment, construction equipment, and automotive.

13726FF125B0300 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
