Energised Lip Seal
|
Product Overview Pioneer Weston’s Energised Lip Seal is a symmetrical seal optimised for heavy duty reciprocating applications with unidirectional pressure. The Energised Lip Seal comprises a high modulus, highly durable, wear resistant, elastomeric jacket, energised by a low modulus split O-ring. The jacket provides superior sealing efficiency and abrasion resistance, whilst the O-ring both transmits system pressure to the contact surfaces and ensures energisation of the seal lips under low pressure or low temperature. The elongated square heal minimises seal roll and improves seal stability. By separating the sealing and energising functions, optimal materials may be selected for each. A typical application would include actuator rod seals. |
