Reduce Standard Groove Size with Parker Diamond Seals

Diamond Seals, Reduce standard groove size with parker diamond sealsParker Diamond Seals are designed to be a compact, robust axial seal alternative to standard cross section seals. Their unique design allows for reduced compression forces, making them ideal for small, lightweight housings in aerospace and military applications. 

Narrow cross section

With a tall and narrow diamond-like cross section, the diamond seal groove is 60% narrower than traditional grooves for comparable seal heights. The narrow cross section of the seal allows it to be used in tight corners and around small holes. The groove width savings allows housing to become thinner, reducing the weight assemblies and is less expensive to machine when compared to standard grooves.

Seal retention

The Diamond Seal has two types of beads located around the profile of the seal. The stabilizer bead prevents the seal from tipping into the groove. The retention bead provides the interference with the groove wall providing exceptional retention.
