Hollow Square Profile Extruded Seals
Brand: Parker HannifinHollow square profile seals offer low closure force and easy installation for many static applications.
Additionally, they offer a compressive force of a lower durometer material and physical property of a higher durometer material.
Therefore, seals with hollow square cross sections can reduce bolt loading and the stress exertion on the mating flanges.
Compressive force can be easily adjusted by changing the wall thickness of the profile without lowering the material hardness.
Features- Clearance gaps are present after assembly
- The gland cross section is more deep than narrow
- Radial interference (squeeze) is needed to assist the end product assembly process
- Low closure force is needed
- Seal cross section surface contact area maximization without overfill
