All Sealtek® flat 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.

Features of Sealtek flat gaskets:
– 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® flat 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 flat gasket limits outlined here.
