About O rings

An O-ring, also known as a packing, or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a disc-shaped cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, creating a seal at the interface, which prevent the leakage of water, fluid, oil, air and other medium.

The O-ring may be used in static applications or dynamic applications where there is relative motion between the parts and the O-ring. Dynamic applications are such as rotating pump shafts and hydraulic cylinder pistons.

O-rings are one of the most common seals used in mechanical equipments as they are inexpensive, easy to make, reliable, and have simple mounting requirements.

An o-ring's size is specially distinguished by inside diameter (I.D) and cross section(C.S) or thickness.

Chose o-ring

The material or composition of an o-ring decide its property. To choose which kind of material should depend on its applications, such as in high or low temperatures, chemical attacks, vibrations, abrasions, and movements ( static or dynamic). O-ring material can be Nitrile (NBR, buna-n), EPDM, Silicone, FPM, FKM, HNBR, NR, PU,CR,FLS and so on. Different material is of different property. If the material is same, the property is subject to the composition. Taking NBR material as an example,  common composition can tolerate temperature -20?-100?, while special composition can tolerate temperature -40?-120?.

We've achieved ISO9000/TS16949 certificates. We could produce both as custom design and AS568?DIN3771?JIS B2401?GB 245201?ISO3601 standards.
