Sealing compounds meet process industry demands

Parker Hannifin - Parker Sales UK product story

Parofluor and HiFluor elastomer sealing compounds combine the elastic properties of elastomers with the outstanding chemical and thermal resistance of PTFE.
Aggressive media, extreme temperatures and pressures, a wide range of required approvals - sealing systems for chemical process engineering have to meet varied demands.
The Parker Seal Group offers a comprehensive portfolio of products and services meeting those requirements - standard as well as customised solutions.
The Parofluor (FFKM) and HiFluor (FKM) compound families are highly resistant elastomer sealing compounds developed by Parker, combining the elastic properties of elastomers with the outstanding chemical and thermal resistance of PTFE.
Spring-energised polymer seals - Flexiseals - suitable for standard O-ring assembly spaces - are available for applications which cannot be covered by elastomer sealing materials.
For the seal's outer jacket, a large number of polymers - often based on PTFE - is available.
The compounds have an extremely low coefficient of friction, broad temperature and chemical resistance and can be adapted specifically to the respective application by the addition of fillers.
The use of a high-grade spring element ensures reliable sealing, even at low pressures and in cryogenic applications.
Resilient metal seals - EnerRings - withstand extreme temperature requirements, high pressures, ultra high vacuums, aggressive chemicals and radioactive radiation for many years.
All materials are developed and tested in our in-house labs.
Using modern simulation techniques, such as finite elements analysis, weaknesses can be detected, and compounds and sealing geometries optimised as early as in the concept phase.
