Product Detail

O-Ring

Simple and Versatile Seal
O-Rings are used extensively throughout industry where pressures, temperatures and tolerances are critical.

Our O-Rings 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.
high performance o-rings 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.

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. O-rings 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 o-ring seals by blocking any potential leak path of a fluid (liquid or gas) between two closely spaced surfaces. The 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 O-Rings 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 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.
