Buna-N Nitrile O-Rings | Low Temp 70 Duro | Mil-Spec -65F to 250F

Low Temp Buna-N O-Rings are nitrile (NBR) seals built to stay flexible in the cold, used to seal fuel, oil, and hydraulic systems where standard nitrile turns stiff and leaks. These 70 durometer O-Rings use Freudenberg N888 compound, a specialty low-temperature nitrile that stays pliable down to about -65F (-54C) and holds up to +250F (+121C), with strong resistance to fuels, oils, and hydraulic fluids. That makes them a solid pick for aerospace, defense, and cold-weather equipment. Sizes are made to AS28775, MS28775, and MS28784 standards, so you can match your groove and order the right mil-spec part fast. Available from an ISO 9001:2015 certified shop.

Operating Temperature: -65°F to +250°F (-54°C to +121°C)
