The quality of PTFE gaskets is mainly reflected in the thickness tolerance. PTFE is not a good sealing material. Of course, the expansion of PTFE is common. The ordinary PTFE gaskets have cold flow properties regardless of recycled materials or pure raw materials. That is, the thickness will change in the long-term, and the screw will be tightly pressed for a period of time, so the thickness tolerance is the preference for the quality of the Teflon gasket, and there is a gasket made of a dispersion resin with a complicated processing technique. It is said that the quality is excellent, but the price will be very expensive.
