For the best value in an economical gasket that is suitable for most general soft gasketing needs, try Ameraflex 1521-C™. The savings can be dramatic!

High quality compressed material composed of fibers with the highest chemical and heat resistance. Nitrile rubber bonded. Outstanding creep resistance at high temperature and high loads provides maximum safety, high torque retention and excellent sealing characteristics.


Ameraflex Also Carries Sealon™

Sealon™ is a gasketing material containing inorganic round beads consistently disbursed throughout a PTFE base. This unique mixture allows for precision control over cold-flow problems inherent with virgin PTFE. The exacting mixture of Sealon™ virtually eliminates the need for retightening. Sealon™ is the result of over 30 years of research, development and testing. This history has brought Sealon™ to the level of perfection our industry demands.
