Insulation Gasket Specifications

Neoprene Faced Phenolic Gasket has been used as standard flat isolating gasket in the oil and gas industries for many years. Soft neoprene rubber sheets are factory applied to both sides of a laminated phenolic retainer providing an effective sealing surface. Phenolic retainer is
1.6mm(1/16”) thickness and neoprene face is 0.8mm(1/32”) thickness on each side, so total
gasket is 3.2mm(1/8”) thickness.


Gasket Characteristics and Advantages:

1. Seals and insulates at pressures up to ANSI 600#.

2. Outstanding insulation properties for cathodic protection.

3. Gasket is sized to the flange bore to protect flange faces from media-induced corrosion and flow-induced erosion. Prevents turbulent flow at flanged connections.
4. Mitigates galvanic corrosion in dissimilar metal flanges.

5. Available to match any flange specification (ANSI, API, BS, DIN, AS, others).

6. Can seal mismatched RTJ Flange with Raised Face Flanges.
