Description

O-rings are circular sealing elements with circular cross-sections, may be used in static applications or in dynamic applications where there is relative motion between the parts and the O-ring. O-ring selection is based on chemical compatibility, application temperature, sealing pressure, lubrication requirements, durometer, size and cost. We offer you a range of elastomeric materials for both standard and special applications which allow the O-Ring to seal practically all liquid and gaseous media.

Design Theory
Orings are one of the most common yet important elements of machine design. They are available in various metric and standard sizes.  Sizes are specified by the inside diameter and the cross section diameter (thickness). The most common standard sizes in the US are controlled by SAE AS568.  ISO 3601-1:2012 contains the most commonly used standard sizes, both inch and metric, worldwide. The UK has standards sizes known as BS sizes, typically ranging from BS001 to BS932. In China, the standard for O ring is GB3452(new standard) and GB1235(old standard).The Japan also has standards sizes known as JIS standard(G series,P series). Several other size specifications also exist.O-rings can be produced by extrusion, injection molding, pressure molding or transfer molding.

Application
O-Rings are used in a variety of fields: they are either used as sealing elements or as energizing elements for hydraulic slipper seals and wipers. Thus, the O-Ring is basically used in every field of industry including aerospace, automotive or general engineering. Today, O-rings are one of the most common seals used in machine design because they are inexpensive, easy to make, and reliable and have simple mounting.

Features
All O Rings are made according to international standard: ISO 3601, AS 568, DIN 3771, JIS B2401, GB3452, BS1516.
Excellent abrasion and wear resistance
Excellent extrusion resistance, accepting even the most significant extrusion gaps
Very good mechanical properties
