diamond seal

Features and Benefits
High sealing pressures for less micro-leakage (often mistaken as permeation) and better
  sealing properties with non-ideal mating surfaces.
Low seal load provides effective sealing even when mating components are easily deflected.
Narrow straight-walled groove width requirement allows more room for other components.
Optimal material usage provides a cost-efficient sealing solution.
Seal retention is achieved through the use of press-in-place design technology.
Easily installed and removed for rapid assembly

Applications
Cover seals    Manifold seals    Face seals with low to moderate system pressures

Inherently self-retaining, Parker Diamond Seal molded seals are designed to be used in molded or machined grooves for face sealing applications. A smaller footprint and narrow cross section result in high seal pressures, low closure forces, and narrow groove width requirements. The unique design optimizes material usage, making Parker Diamond Seal molded seals highly cost efficient. In addition, they are particularly effective when mating surfaces are less than perfect. Parker Diamond Seal molded seals can be custom designed to fit both round and complex manifold shapes in the optimal size for your application.
