E4 PROFILE SEAL

E4 PROFILE SEAL

Parker's E4 profile (piston) and E5 profile (rod) are non-symmetrical seals designed to seal both lubricated and non-lubricated air. To ensure that critical surfaces retain lubrication, the radius edge of the lip is designed to hydroplane over pre-lubricated surfaces. The standard compound for the E4 and E5 profile is Parker's proprietary Nitroxile ELF compound N4274A85. This compound is formulated with proprietary internal lubricants to provide “Extreme Low Friction” and excellent wear resistance. This compound provides extended cycle life over standard nitrile and carboxylated nitrile compounds.
