ISO 3601 Metric O-Rings

July Replaced By: On Chart 50 in our O-ring guidethe reference numbers highlighted in red indicate those sizes covered by:. The standard level is Grade N. The use of nano-PTFE in fluoroelastomers and perfluoroelastomers improves abrasion resistance, lowers friction, lowers permeationand can act as clean filler. This expansion causes blisters and ruptures on the surface of the seal.

O-rings are available in various metric and inch standard sizes. Static applications of O-rings may include fluid or gas sealing applications in which: Nano-technology -rubber is one such new frontier. This was famously demonstrated on television by Caltech physics professor Richard Feynmanwhen he placed a small O-ring into ice-cold water, and subsequently showed its loss of flexibility before an investigative committee.

At Superior, we pride ourselves on our precision o-ring range which exceeds the cross-sectional tolerances for the following dimensional standards.

Please consult our Quality department for specific requirements on sales superiorltd. All documentation for dispatch to the customer conforms to the ISO standard. In some high-temperature applications, O-rings may need to be mounted in a tangentially compressed state, to compensate for the Gow-Joule effect. As long as the pressure of the fluid being contained does not exceed the contact stress of the O-ring, leaking cannot occur.

O-ring materials may be subjected to high or low temperatures, chemical attack, vibration, abrasion, and movement. However, the temperature of the rubber O-rings remained significantly lower than that of the surrounding air.

Already, there are elastomers filled with nano-carbon and nano- PTFE and molded into O-rings used in high-performance applications. An O-ring 36001-1, also known as a packingor a toric jointis a mechanical gasket in the shape of a torus ; it is a loop of elastomer with a round cross-sectiondesigned to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface. Lundbergthe inventor of the O-ring, received the patent.

Many O-rings now come 360-11 batch and cure date coding, as in the medicine industry, to precisely track and control distribution. Superior is able 36601-1 provide materials compliant to current European and Worldwide legislative requirements e. Wikimedia Commons has media related to O-rings. Environmental compliance Superior is able to provide materials compliant to current European and Worldwide legislative requirements e.

Synthetic rubbers – Thermosets:. At the low end, nearly all engineering materials become rigid and fail to seal; at the high end, the materials often burn or decompose. Superior is accredited by ISO Inside diameters, cross-sections, tolerances and designation codes Status: This style of seal is sometimes less expensive to manufacture with certain materials and molding technologies compression moldingtransfer moldinginjection moldingespecially in low volumes.


Retrieved 9 April This allows a high local stress, able to contain high pressure, without exceeding the yield stress of the O-ring body. Class B allows production of O-Rings in technically acceptable and economical metric sizes and inch sizes, which izo then fit into metric grooves.

On the night before the launch, exceedingly low air temperatures were recorded.

Customers who bought this product also bought BS EN Space Shuttle Challenger isso. This website is best viewed with browser version of up to Microsoft Internet Explorer 8 or Firefox 3. O-rings and all other seals work by creating positive pressure against a surface thereby preventing leaks. When squeezed upon installation, they seal with 4 contact surfaces—2 small contact surfaces on the top and bottom.

Inside diameters, cross-sections, tolerances and designation codes. For sealings, there are variations in cross-section design other than circular.

Retrieved from ” https: The shape can have different profiles, an x-shaped profile, commonly called the X-ring, Q-ring, or by the trademarked name Quad Ring.

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 jso.

Self-contradictory articles from November All ios articles Commons category link is on Wikidata. In the Superior o-ring size list, the internal diameters conform to ISO tolerances and the cross section diameter has a reduced tolerance.
