Flat Flange Gaskets
Flat Flange Gaskets
Non-Asbestos Compressed Fibre Gaskets (NACF)
Our Non-Asbestos Compressed Fibre (NACF) Gaskets are fabricated from high-grade aramid/synthetic fibers bound with elastomeric rubbers (NBR, SBR, or EPDM). Designed to replace asbestos gaskets in eco-compliant industrial applications, NACF gaskets provide high torque retention and reliable sealing across flat face and raised face pipe flanges.
