Gaskets and Joints

All the SEALTEK gaskets are manufactured with the most advanced production methods based on synthetic fibers and elastomeric binders, responding to today's rigorous demand of non-asbestos materials.

Pressure and temperature limits are indicative and should never be combined at their maximum values
Surface compression should not exceed the maximum pressure of each individual material as this would eliminate the recovery ability of the gasket.
Surface to be sealed must be free of pitting, flat, smooth, clean of dirt or old gasket deposits as the presence of any of these would compromise proper sealing.
Parallel flanges are a necessary condition as if not parallel, premature gasket failure will occur. It is strongly reccomended that a torquewrench is used when tightening.
No antisticking agent should be applied when using Sealtek® Gaskets as this would compromise their performance. All Sealtek® Gaskets are pre-treated with a nonstick agent and do not require any additional protection
Consult a Sealtek® specialist for any application that might exceed the gasket limits outlined here.
