THIS DATA IS FOR GUIDANCE ONLY!
The ability of a gasket material to effect a seal depends not only on the quality of the material, but also on the thickness of the material, the design of the flanges, the amount of pressure exerted on the gasket by the bolts, and how the gasket is assembled into the flanges and tightened.
Please consult our technical service staff who will be pleased to advise you on the most suitable method.

This test was developed to assess the behavior of gaskets when subjects to surface stress in cold and hot conditions. In this test the load is maintained as the gasket relaxes and the temperature increases. This subjects the gaskets to more severe conditions than the ASTM F 38B test. Measurements are made of the decrease in thickness under a load of 3625 psi at a temperature of 73°F and the additional decrease in thickness caused by heating to 572°F under constant load.
