GASKET, KLNGR C4401, 18.00" 300# RF

Ordered as 13850RF062B1800FC, this is a green Klingersil C-4401 Class 300 ring face Flange Gasket measuring an 18 inch nominal pipe size, a Class 300 pressure rating, and a thickness of 0.062 inch. The flange gasket fills the microscopic imperfections in flange faces so the joint holds pressure. Source specification: NPS, 0.062 THK.

Klingersil C-4401 is specified here for excellent torque retention and low creep relaxation, calendered, compressed fiber structure bound with elastomer. It resists a broad range of process chemicals, hydrocarbons, and steam and hot water. Applications involving service beyond the published pressure-temperature envelope or strong oxidizing acids in some grades call for a different compound.

Typical settings include chemical processing, steam and hot water systems, and power generation.

13850RF062B1800FC ships individually. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
