Uxcell M16 21.5x13.8x3mm Carbon Steel Nitrile Butadiene Rubber Bonded Sealing Washer Gasket 50 Count

Uxcell Carbon Steel Nitrile Butadiene Rubber Bonded Sealing Washer Gasket Hardware Washer Type : Plain Washer The nitrile rubber is bonded by heat and pressure to the outer ring which holds it in place. This structure increases resistance to bursting increasing the pressure rating of the seal. Because the bonded washer itself acts to retain the gasket material there is no need for the parts to be sealed to be shaped to retain the gasket. This results in simplified machining and greater ease of use as compared to some other seals such as O-rings.
