Static crush seal design
WebA crush seal is a unique style of static seal. This seal works by permanently deforming an o-ring into a small space, typically triangular in cross section. This method does not need … WebMar 16, 2024 · The design parameters for both static and dynamic radials are mostly similar. The important design factors to take into account when designing a static or dynamic radial seal include squeeze, fill, stretch, gap size (also known as clearance gap) and the angle of installation chamfer.

WebDesign Chart 4-6: Static Crush Seal Grooves Triangular Grooves This type of crush seal is used where cost and ease of machining are im- portant. The O-Ring is confined in a triangular recess made by machining a 45 degree angle on the male cover. The OD of the ring should be about the same as the recess diameter. WebCrush Seal Gland Designs Because O-rings are asked to perform in an unbelievably wide range of applications, it is not always possible to fit a traditional rectangular O-ring …
WebFace Type Seals . The face seal design chart below explains the hardware dimensions to use for an O-ring seal when the groove is cut into a flat surface. For designing systems which contain internal pressure, like the example below, the groove's outside diameter (OD) is primary, and the groove's width then determines the inside diameter.

In static seals, where the O-Ring is not in axial motion in the bore, the recommended maximum compression is approximately 40%. In dynamic seals, such as a piston moving inside a cylinder, the recommended maximum compression is somewhat less at 30%. porcher e902801WebA static triangular crush seal groove is a simple design and ideal when space is limited and/or wall thickness is too thin for a conventional groove. It achieves the same sealing efficiency with either internal or external pressure.
