O RING NBR

(NBR) O-Rings, Are one of the most commonly used sealing elastomers due to resistance to petroleum-based fuels and lubricants and its relatively low price. Nitrile elastomers are copolymers of acrylonitrile and butadiene. There are a number of common variations of nitrile compounds. Nitrile O-rings may also come in a metal detectable variation, while retaining the same qualities as the general Nitrile o-ring compound.

For Applications requiring o-rings with high visibility, High-Visibility Nitrile O-rings are recommended. High-Visibility o-rings maintain properties identical to its original compound, with the addition of a distinguishable neon green hue.

Standard NBR O-Rings are usually sulfur-cured. Sulfur-cured compounds offer better low-temperature properties but are more prone to hardening with high temperatures. Peroxide-cured nitrile o-rings have better heat resistance and lower compression sets but are more expensive and more difficult to process. Standard materials in stock include sulfur-cured 70 & 90 durometer .

Tempreture: -55c up to +135c also there is other hardness grade -29c up to +100c
