Inertex® OPRA (One Piece Reduced Area) 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 opportunities 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 affect and maintain a seal.
Product Benefits:
- Seals at low bolt loads
- Maintains tight seal even with varying flange conditions
- Conforms to irregular surfaces
- Protects the flanges from cracking
- Priced lower than other low bolt load gaskets on the market
- High blowout and creep resistance
