  Product Description  ROHS Rubber EPDM O Ring   Simple and versatile seal

Our precision rubber o ring are used extensively throughout industry where pressures, temperatures and tolerances are critical.   Our rubber o ring are specially manufactured for both static and dynamic applications and offer a wide range of properties, including excellent compression set characteristics, ability to withstand aggressive process media, and a long trouble-free operating life. Ours high performance rubber o ring are available in a variety of advanced materials: NBR(Buna-N), HNBR, VITON, Silicone, EPDM, Teflon(PTFE), Encapsulated O-Ring,etc, in both standard and custom sizes.

        rubber o ring Application Functional Description An o-ring is a simple and versatile ring-shaped packing or sealing device with a circular cross section, from which the "O" in its name is derived.  rubber o ring function as compact and reliable sealing devices by absorbing the tolerance stack-up between closely mated surfaces in both dynamic (moving) and static (stationary) applications.

An rubber o ring seals by blocking any potential leak path of a fluid (liquid or gas) between two closely spaced surfaces. The rubber o ring is generally installed in a machined groove in one of the surfaces to be sealed. As the two surfaces are brought together, forming a gland, they squeeze the cross section of the o-ring.   Static Sealing Most rubber o ring  are used in static service (the O-Ring and metal surfaces remain relatively fixed). They may be applied as face seals or radial seals. In face seal applications, the O-Ring should seat against the low pressure side of the groove.   Dynamic Sealing The rubber o ring moves relative to the mating surface. A moving seal may be further classified by the type of motion: reciprocating, oscillating, or rotating. The greatest number of dynamic seals are used in reciprocating service in cylinders, valves, and linear actuators. Oscillating motion is encountered in swivels and valve stems. When an O-Ring is used on a rotating shaft, it should be limited to light duty where the shaft speed is low and some fluid bypass is acceptable.   Durometer Selection 70-durometer hardness should be used wherever possible as it offers the best combination of properties for most O-Ring applications. Softer compounds stretch easier and seal better on rough surfaces. Harder compounds offer greater abrasion resistance and resistance to extrusion.    If you require further information or enquire, please contact us   Our Product   Company Information Our Company and the equipment
