Instead, higher mounting forces are used and the ring fills the whole groove. Chemical attack can degrade the material, start brittle cracks or cause it to swell. Nano-technology -rubber is one such new frontier.
BS ISO 3601-1:2008
O-rings are one of the most common seals used in machine design because they are inexpensive, easy to make, reliable and have simple mounting requirements. The O-ring may be used in static applications or in dynamic applications where there is relative motion between the parts and the O-ring.
Sign up for products and services news. With our expertise we can closely define and control seal tolerances and surface characteristics. Process – Process Equipment.
BS , BS ISO and SAE AS O-rings
Transmissions hydrauliques et pneumatiques. O-rings are available in various metric and inch standard sizes. Revised – Inside diameters, cross sections, tolerances and designation codes: Spiral Failure — Found on long-stroke piston seals and — to a lesser degree — on rod seals.
News from John Crane”. For example, carbon nanotubes are used in electrostatic dissipative applications and nano-PTFE is used in ultra pure semiconductor applications. On Chart 50 in our O-ring guidethe reference numbers highlighted in red indicate those sizes covered by: American National Standard Aerospace size standard for O-rings Although the basic range is in inches, the O-rings can of course be used for sealing metric dimensioned components.

In reality, in the market place there are many 3601–1. Air filter Blowoff valve Boost controller Butterfly valve Centrifugal-type supercharger Cold air intake Dump valve Electronic throttle control Forced induction Inlet manifold Intake Intercooler Manifold vacuum Naturally aspirated engine Ram-air intake Scroll-type supercharger Short ram air intake Supercharger Throttle Throttle body Turbocharger Twin-turbo Variable-geometry turbocharger Variable-length intake manifold Warm air intake.
Metric O-rings are usually defined by the internal dimension x the cross section.

As long as the pressure of the fluid being contained does not exceed the contact stress of the O-ring, leaking cannot occur. The escaping high temperature gas impinged upon the external tank, and the entire vehicle was destroyed as a result. Our Chart 50 tables include suggested metric shaft and cylinder sizes for which each individual O-ring is suitable. At the low end, nearly all engineering materials become rigid 3061-1 fail to seal; at the high end, the materials often burn or decompose.
Elastomers are sensitive to ionizing radiation. In other projects Wikimedia Commons. Society of Automotive Engineers SAE Aerospace Standard AS  specifies the inside diameters, cross-sections, tolerances, and size identification codes dash numbers for O-rings used in sealing applications and for straight thread tube fitting boss gaskets.

The failure of an O-ring seal was determined to be the cause of the Space Shuttle Challenger disaster on January 28, Your basket is empty. By dissipating these charges, these materials, which include doped carbon-black and rubber with metal filling additives, reduce the risk of ignition, which can be useful for fuel lines.
