2. O Ring Scope
O-ring for installation in a variety of machinery and equipment, at the specified temperature, pressure, and various liquids and gases, in stationary or moving under the seal. In machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery, as well as various types of instrumentation, the large number of applications with different types of seals components. O-ring is mainly used for static seals and reciprocating seals. Seal for rotary motion, is limited to low speed rotary sealing device. O-ring is usually installed on the inner circle in the cylindrical or rectangular cross-section of the groove from seal. O-ring in the oil, acid, grinding, chemical erosion and other environmental still play a good sealing, damping effect. Therefore, O-ring hydraulic and pneumatic drive system most widely used as a seal.
O-ring Seals compared with other types, has the following advantages: - for a variety of seal forms: static seals, dynamic seals for a variety of uses materials, dimensions and grooves are standardized, interchangeable - for multi- kind of movement pattern: rotation, or a combination of axial reciprocating movement (such as rotating reciprocating movement combinations) - suitable for a variety of different sealing medium: oil, water, gas, chemical media or other mixed media through the appropriate choice of materials and rubber proper formulation design, realization of oil, water, air, gas and a variety of chemical mediators effective seal. Wide temperature range (- 60 °C ~ + 220 °C), pressure up when using fixed 1500Kg/cm2 (with reinforcement ring and use). - Designed to be simple, compact, easy assembly and disassembly O-ring cross section structure is extremely simple, and there is self-sealing, reliable sealing performance. Since O-ring structure itself and installation parts are extremely simple, and has formed a standardized, so replacement is very easy to install. - Material varieties can be selected according to different fluid: a nitrile rubber (NBR), Viton (FKM), silicone rubber (VMQ), ethylene-propylene rubber (EPDM), chloroprene rubber (CR), butyl rubber (BU), polytetrafluoroethylene (PTFE), natural rubber (NR), etc. - Cost - dynamic friction is relatively small

Function of Rubber Back-Up Rings
Rubber back-up rings are designed to prevent extrusion in rubber o-ring sealing systems.
Rubber O-Rings generally serve as effective seals for dynamic and static applications in hydraulic and pneumatic systems equipment. One big drawback of such o-rings is their tendency to extrude into the clearance of mating surfaces when subjected to increasing pressures.
The degree of extrusion is a function of o-ring hardness, clearance of mating parts and fluid pressure.
Another variable that must be considered in determining the need for back-up rings is the operating temperature. Elevated temperatures (160 degrees F and higher) impose a severe burden on the physical and mechanical properties of rubber o-rings which further increases their tendency to extrude.
The combination of high pressures and high temperatures is a common occurrence in present day fluid systems. Moreover, the trend is toward still higher pressures and longer resident times at elevated temperatures. This places more emphasis on the role of the Back-Up Ring in preventing o-ring extrusion.
There are three basic types of Rubber back-up rings in use: single turn (scarf cut), multi-turn (spiral cut) and solid (uncut) configurations.
Heavy Duty Back-Up Rings
Heavy duty back-up rings are configured with a greater T (axial thickness) dimension. The extra thickness provides more extrusion protection for o-rings. These rings are interchangeable with MS27595, MS28774, MS28782 and MS28783 backup rings used in MIL-G-5514 packing glands. Heavy duty back-up rings are available in solid (uncut) and in the single turn (scarf cut) configurations.
In addition to the military standards, we supply three series of extended dash-size standards which provide back-up rings for all o-rings in the Aerospace Standard AS-568A Uniform Numbering System.
These configurations have proven very useful to fluid systems designers because of the added flexibility in size selection.
Because extended sizes usually are available, industrial users are assured of the same quality and service that applies to the most sophisticated aerospace applications.
Filled Back-Up Rings
For applications where sealing systems are subjected to severe duty cycles, or where pressures exceed 3,000 psi and temperatures are above 275 degrees F, filled Rubber back-up rings are very useful.
In addition to the more common fills such as glass fibers, considerable experience with back-up rings of Nylon, Kel-F, FEP, UHMW and Others. We have produced the very standards using these materials as well as more specialized compounds of Rubber.
Care should be taken to be sure that the compound chosen is compatible with the gland or rod materials of construction. There is no point in over designing components that may cure extrusions, but produce abrasion or wear problems.
