APG stocks the 13850RF125B0050FC, a green Klingersil C-4401 Class 300/400/600 ring face Flange Gasket measuring a 0.5 inch nominal pipe size, a Class 300/400/600 pressure rating, and a thickness of 0.125 inch. A flange gasket fills the microscopic imperfections in flange faces so the joint holds pressure.
As a material, Klingersil C-4401 offers a calendered, compressed fiber structure bound with elastomer, excellent torque retention and low creep relaxation. The compound resists a broad range of process chemicals, steam and hot water, and hydrocarbons. It should not be specified for service in strong oxidizing acids in some grades or service beyond the published pressure-temperature envelope.
Maintenance and OEM teams specify it across pulp and paper, steam and hot water systems, and refining.
13850RF125B0050FC ships individually. Check the compound against your process media, pressure and temperature before committing to a design. Not finding the exact configuration you need? APG cross-references from prints, samples and competitor part numbers.
