Hydraulic Cap Seals

Rod & Piston Cap Seal

Dura-Cap™ design is used when exceptional wear life is required under high pressure applications. The Dura-Cap™ Cap Seal profile distributes the contact load provided by the elastomer compared to the O-ring energizer profile. This design is used in high pressure hydraulic applications. This will fit into Mil-G-5514 or AS4716 standard seal hardware dimensions. Inquire for non-standard glands.
