*GASKET, KLNGR C4430, 6.000" 150# RF

This flange gasket is supplied in green Klingersil C-4430 Class 150 ring face with a 6 inch nominal pipe size, a Class 150 pressure rating, and a thickness of 0.125 inch, catalogued under part number 13C4430RF125A0600. It fills the microscopic imperfections in flange faces so the joint holds pressure. This item is further identified as NPS,0.125 THK.

The compound resists steam and hot water, hydrocarbons, and a broad range of process chemicals. That behavior comes from the compound itself: Klingersil C-4430 is known for clean release and easy removal at teardown, a calendered, compressed fiber structure bound with elastomer. Exposure to strong oxidizing acids in some grades or service beyond the published pressure-temperature envelope will shorten service life.

Maintenance and OEM teams specify it across refining, power generation, and pulp and paper.

Reference part number 13C4430RF125A0600 when ordering; the item is sold individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
