The Nitrile Butadiene (NBR) compound has excellent resistance to a wide variety of fluids, good tensile strength, high elongation, low compression set, and excellent resistance to abrasion and tear
ORB O-Rings are used in static service (the O-Ring and metal surfaces remain fixed)
This o-ring provides a seal for straight-thread tube fittings on a boss
Numbering System: The two digits after the -9 represent the tube size O.D. in 16ths of an inch. For example -905 is sized for a tube O.D. of 5/16". The one exception is for -901 where the Tube Size O.D. is 3/32"
