Valve seats, gland packing, O-rings, POM components
Valves rely on a handful of plastic components to seal, guide and operate reliably across millions of cycles. We supply machined PTFE, PEEK and POM parts for valve seats, plugs and stems, plus the gland packing, o-rings and seals that keep them tight. Suitable for ball valves, butterfly valves, gate valves and control valves across the chemical, water, oil and process industries.
Specific applications across the industry where our materials are commonly specified.
Machined PTFE, PTFE-alloy and PEEK seats — chemically inert, low friction and long cycle life. Standard sizes from 1/4" to 12" plus bespoke.
Gland packing in PTFE, PTFE/graphite, pure graphite and aramid for stem stuffing boxes. Steam, hot oil, slurry and chemical service.
FKM, NBR, EPDM elastomer seals plus FEP/PFA encapsulated o-rings for aggressive media and high-temperature service.
Machined POM and PEEK plugs, discs and trim parts. Wear resistant, dimensionally stable and easy to manufacture in series.
PTFE-filled and self-lubricating POM/PEEK bushings — eliminates external lubrication on valve stems.
Cut and machined PTFE / PTFE-alloy gaskets — full pH range, FDA-compliant grades available.

The default seat and seal material — inert across full pH, low friction, FDA grades available.
When higher mechanical strength and creep resistance are needed at elevated temperatures.
Machined plugs, discs and trim — dimensional stability and excellent machinability.
Stem sealing in PTFE, PTFE/graphite, pure graphite, aramid and carbon fiber.
FKM, NBR, EPDM and encapsulated FEP/PFA — choose by media and temperature.
Reinforced PTFE grades for higher pressure and longer life on critical valve seats.
