Product Overview
Spring-energized PTFE seals solve sealing problems where elastomer O-rings fail — cryogenic valves, high-pressure compressors, semiconductor equipment and aggressive chemical service. The manufacturers listed here CNC-machine jackets from virgin and filled PTFE, UHMW-PE or PEEK, energized by V-springs, cantilever springs or canted-coil springs selected per pressure and friction requirements. Operating envelope spans -260°C to 260°C and pressures to 700 bar depending on configuration. With fully machined production, single-piece prototypes and small batches are economical, and drawings in STEP format can be turned around in 5–7 working days. This makes the format a practical fit for equipment R&D phases, aftermarket sealing upgrades and low-volume specialty valve programs.
