Diamond & H Seals

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.

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

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

Parker H-Seal™ molded seals can be used in molded or machined grooves for face seal applications. They will fit traditional dovetail grooves or straight-walled grooves. If desired, Parker H-Seal molded seals can be self-retaining with the addition of retention ribs. The redundant sealing beads offer stability and resistance to twisting, which is particularly important with large profile seals. The small contact points of Parker H-Seal molded seals generate high seal pressures, making them particularly effective when mating surfaces are less than perfect. 
The Parker H-Seal cross section can be used in a round profile or in custom-designed manifold systems. Parker H-Seal cross sections can be refined to meet the specific seal load and/or system pressure requirements that your application demands.

Applications 
• Cover seals        • Manifold seals        • Perimeter seals
• Face seals with low to high system pressures

Features and Benefits
•  High sealing pressures for less micro-leakage (often mistaken as permeation) and better 
   sealing properties with non-ideal mating surfaces.
•  Application-specific seal loads can be achieved by adjusting the cross-sectional geometry 
   and/or material selection.
•  Seal retention is achieved through the use of “press-in-place” design technology in straight-
   walled or dovetail grooves.
•  Easily installed and removed for rapid assembly.
