The 13C4430RF125A1000 is a green Klingersil C-4430 Class 150 ring face Flange Gasket measuring a 10 inch nominal pipe size, a Class 150 pressure rating, and a thickness of 0.125 inch. This flange gasket compresses between two pipe flanges under bolt load to create a leak-tight joint. This item is further identified as NPS,0.125 THK.
Expect good resistance to hydrocarbons, a broad range of process chemicals, and steam and hot water. That behavior comes from the compound itself: Klingersil C-4430 is valued for reliable sealing on flanges with modest surface finish and a calendered, compressed fiber structure bound with elastomer. Exposure to service beyond the published pressure-temperature envelope or strong oxidizing acids in some grades will shorten service life.
You will find this material specified across chemical processing, power generation, and refining.
