This performance test measures the behavior of rPTFE and PTFE gaskets in a real world environment. The chart below shows a comparison between conventionally skived PTFE and Tealon. The gaskets we tested simulated a real world application including thermo-cycling. The skived PTFE gasket showed a very high leak rate, losing 60% of its initial pressure by the end of the test.

The Tealon® gasket lost only 6% of its initial pressure by the end of the test and showed a leak 10 times less than that of the skived PTFE gasket. The pictures below, show the gaskets after the test and exhibit the dimensional stability of Tealon as compared to the noticeable creep of the skived PTFE gasket.

Temperature cycles from 30º C to 200ºC, with seating stress of 5000psi and using a gasket thickness of 1/8″.
