The INERTEX family of gasketing and sealing products are produced by proprietary processes protected by both u.s. and world. All INERTEX products share the following typical properties:

• 100% expanded virgin PTFE • Pressure range, full vacuum to 3,000psi • Low coefficient of friction (.02 like wet ice)
• Temperature range, -450°F to +600°F • Extremely soft, excellent conformability • FDA suitable (FDA 21 CRF 177.1550)
• pH range from 0 to 14 • Little creep or cold flow • No aging or hardening in service

INERTEX® OPRA REDUCED AREA GASKETS

The OPRA® gasket designs have been developed in response to the use limitations and high cost of other low torque composite gaskets. OPRA® gaskets will have broad opportunity for sealing plastic and thin flat face metal vessel flanges where other PTFE based gaskets require excessive assembly bolt loads. The OPRA® has been patented which covers the unique approach of dramatically reducing the contact area of gaskets intended for low bolt sealing applications including FRP, PVC piping and vessels. The reduced gasket area results in a proportionate reduction in the bolt load (torque) necessary to effect and maintain a seal.

OPRA® GASKETS REQUIRE LESS BOLT TORQUE THAN ANY OTHER 100% PTFE GASKET CURRENTLY IN THE MARKET.
