Type "E" (Full Face) Gaskets

Type "E" gaskets perfectly center on precisely located bolt holes. Since their outside diameters are the same, foreign material is prevented from "shorting" the flange insulation.

Type "F" Gaskets

Type "F" gaskets are made without bolt holes, to fit tightly inside the overall bolt hold circle of the flange faces. The outside diameter of the gasket fits tightly in place, assuring a well centered position.

Jock™ O-Ring Gaskets

BEFORE

The flange face contacts the crown of the elastomer seal ring. As the bolts are tightened, the flange face deforms the seal crown into the molded voids.

AFTER

The flange faces are in complete contact with the seal retainer, thus encapsulating the seal elements in conjunction with the retainer grooves. The elastomer, because of its resiliency and pressure from the line fluid, attempts to return to its original shape and effects a positive O-ring type seal.

PROBLEM SOLVED

• Fewer service calls due to leaking and "shorting" flanges.
• Positive sealing through a wide range of fluctuating temperatures.
• Maintenance versatility and positive sealing in difficult situations.
• Longest fire life of any insulating gasket.
• Positive seals and zero environmental leakage
