Our PTFE stem packing, made in the USA from 100% PTFE resin without fillers, is designed to minimize leakage and allows for greater compressibility under lighter loads. It can accommodate temperatures from -450°F to 500°F, pressures up to 1450 psi, and has a pH range of 0-14, with optional graphite filler available. For inquiries, contact us via phone or email.

1. PTFE Stem Packing
Description:
Our PTFE stem packing manufactured in the USA from 100% PTFE resin with no fillers
or additives and is extruded, eliminating the leak path potential allowed by conventinal
spiral tape wrapping. Our PTFE stem packing is also slightly expanded allowing grater
compressibility under lighter compression loads.
For customers requiring Graphite filler, Graphite can be added with loading levels as
high as 20% by weight
