Mar 14, 2013· When the pressure on an o-ring is increased to the point that it can no longer resist being extruded into the diametrical gap, and to compensate for loose fitting components, the use of backup rings to block the diametrical clearance gap and provide support for the o-ring may be a viable solution A backup ring is made of a harder material than the o-ring itself, but sufficiently resilient to.
The table on our detailed information page recommends dimensions for dynamic rotary seal glands by AS-568A O-ring dash numbers O-rings serving in a dynamic rotary gland should consider the surface finish, speed of shaft, and pressure Datwyler Sealing Solutions USA provides the basic o-ring dynamic rotary gland design for these applications.
This double acting seal design can be accommodated by a standard O-ring groove The design helps prevent extrusion and spiraling up to 5,000 PSI Hi-Tech Seals also offers a locking T-seal profile, which aids in the installation process Standard T-seals are composed of a Nitrile sealing element and two split Nylon Back-up rings A popular.
Back-Up Rings for AS568 O-Rings MFP Seals produces Backup rings that are designed to keep O-Rings from extruding as well as Backup rings for U-Cups applications These Back-up Rings are produced in either a contoured design, Split (MS28774) or Solid (MS27595) configuration and a wide range of materials are used to fit your application.
O-Ring Having stabilized sealing performances and the ability to withstand applications under high pressures, o-ring is inexpensive, long lasting, and can offer extreme advantages from.
Mobile inPHorm - Parker's Design Tool & O-Ring Calculator O-Ring Design Procedure using Mobile inPHorm Parker recommends utilizing our design tools (Mobile inPHorm and the O-Ring Selector)design software to guide the user through the design and selection of an O-ring and corresponding seal gland.
An O-Ring is described by its inner diameter, its outer diameter, its material hardness , Design Guidelines , Install backup rings in the groove with the O-Rings to prevent extrusion Use harder O-Rings compound These modifications, however, have their drawbacks For example, reducing system-operating pressure may affect the operational.
Back-Up Rings buy on-line or call 208-413-6377 - back-up rings provide extra extrusion resistance, and prevent damage to O-Rings in applications that have high pressures, larger extrusion gaps, and/or high temperatur Extrusion failure is a very common type of O-ring failure.
As well as the chemical volume swell or shrinkage of the O-Ring Choose between over 30 construction part materials and 11 O-Ring compounds! Ask ERIKS For more information on the O-ring Groove Calculator or other products please visit our contact page or.
