Spring seals comprise of a high modulus elastomer and two integrated anti-extrusion springs, they are used to effectively seal applications that are subject to:
- Large clearance gaps
- High pressure (bi-directional)
- Restricted access for seal installation
- Chemical attack by oilfield media
PPE spring seals are available in unique combinations of elastomer materials not found elsewhere.
- Elastomers: HNBR, EnDura® FKM and Perlast® FFKM.
- Springs: PEEK, Inconel Alloy or Stainless steel 316.
Steel springs offer optimum strength, however PEEK springs are the perfect option for low wear applications where metal-to-metal contact with the housing is a concern.
