GASKET, KLNGR C4401, 01.50" 150# RF

The 13850RF093A0150 is a green Klingersil C-4401 Class 150 ring face Flange Gasket measuring a 1.5 inch nominal pipe size, a Class 150 pressure rating, and a thickness of 0.093 inch. This flange gasket seals a bolted flange connection across the full pressure rating of the class. Source specification: NPS, 0.093 THK.

The compound resists steam and hot water, elevated flange loads, and a broad range of process chemicals. That behavior comes from the compound itself: Klingersil C-4401 is widely chosen for reliable sealing on flanges with modest surface finish and a calendered, compressed fiber structure bound with elastomer. Applications involving strong oxidizing acids in some grades or service beyond the published pressure-temperature envelope call for a different compound.

It sees regular use in chemical processing, power generation, and refining.
