O-Ring seals are suitable for various mechanical equipment. It has sealing function in static or motion state. When it was in the medium of specified temperature, pressure, different liquid and gas. There have many sealing elements used in machine, ship, automobile, aerospace equipment, metallurgical machinery, chemical machinery, construction machinery, building machinery, mining machinery, petroleum machinery, plastic machinery, agricultural machinery and various instruments and apparatus. O-Ring seals mainly used for static sealing and reciprocating motion sealing. When it used in rotary sealing, it was only limited in low speed rotary sealing device. O-Ring seals generally installed in the groove of rectangle cross section. O-Ring seals have good sealing performance in the situation of oil resistance, acid and alkali resistance, wear resistance, chemical resistance. O-Ring seals are most widely used in hydraulic and pneumatic system.

Nitrile is the most widely used elastomer in the seal industry, and commonly used in o-ring and sealing applications. The popularity of nitrile is due to its excellent resistance to petroleum products and its ability to be compounded for service over a temperature range of -22°F to 212°F. Nitrile provides excellent compression set, tear, and abrasion resistance. The nitrile o-ring is commonly referred to as a Buna o-ring, or NBR o-rings. Forever Seals offers a complete selection of both the standard AS568 o-ring and metric o-ring sizes.
