RING GASKETS cut from non-asbestos style in Green or Blue for 150 # class flanges
Maximum Temperature 700 F
Maximum Pressure 1500 PSI
Strong flexible gaskets made with Aramid Fiber and NBR rubber binder.
(IBC = Inner Bolt Circle, round seal without screw holes)
The centering of the seal is accomplished by the outer diameter of the gasket in combination with the nominal screw diameter,
keeping the gasket (ring) in place. Please note that a higher surface pressure can be applied to the seal by using IBC form using the same bolt-torque values. Since the surface pressure has a decisive influence on the sealing-class, an IBC seal is generally the more advantageous option.
