Parker Diamond Seals are designed to self-retain in molded or machined grooves. They are custom molded to fit both round and complex groove paths with the potential to seal multiple ports with just one seal.

Parker Diamond Seals are designed to self-retain in molded or machined grooves. They are custom molded to fit both round and complex groove paths with the potential to seal multiple ports with just one seal.

Description
    Many seal alternatives have limited or no self-retention capabilities which can lead to rework, warranty, and customer dissatisfaction as a result of pinched or missing seals. Common seals and gaskets require wide grooves and flanges to ensure stable geometry and/or maintain adequate volume fill ratios. Wide flanges drive larger enclosures and reduce design flexibility.

    Parker Diamond Seals provide a high performance seal with superior compliance in narrow grooves to handle as-molded and as-cast tolerance variation. Optional integrated retaining ribs provide unmatched retention sufficient for the most demanding assembly line or shipping conditions. Diamond Seals function at much lower loads than gaskets for greatly reduced creep. Structural loads are carried through hard contact between mating components, preventing seal compression set from affecting bolt tension. For service, high-quality elastomeric seals come out quickly and cleanly. Diamond Seals can be molded in almost all Parker compounds and can be tailored to target the right balance of seal load, compli¬ance, chemical resistance, and temperature range.
