Very powerful Angle Flange Gaskets to seal ducting together.
Angle Flange Gaskets create a static seal between two flange faces by filling the microscopic spaces and irregularities of the flange faces, and then forming a seal that is designed to keep liquids and gases within the ducting.
The standard gasket is constructed of black nitrile, a conductive material that has a temperature range of -20°F to 250°F. Red Silicone is also available for higher temperature applications as it has a temperature range of -65° to 450°.
For use with Nordfab:
Gasket dimensions should match Angle Flange dimensions and one gasket should be used per joint.
