Lip Seals
Energized lip seals comprise of a high modulus elastomer (or high grade engineering plastic) jacket, and a low modulus elastomer O‑ring energizer.
The low modulus O‑ring energizes the jacket under low pressure conditions to increase the sealing force allowing them to be used in low and high pressure applications.
PPE offers energized lip seals in a variety of profiles to suit your application – or enquire about our custom component design service.
About energized lip seals
Energized lip seals provide a versatile sealing system for uni‑directional pressure applications in either static or reciprocating dynamic conditions. Energized lip seals are symmetric in their cross section and so they can be used in both rod or piston grooves. Backup rings can be used in conjunction with energized lip seals to enhance extrusion resistance.
There are various profiles of energized lip seals available with differing qualities depending on application requirements.
