-115 BLACK BUNA 50D O-RING

The H50115 is an AS568-115 black Buna-N (Nitrile) 50 Shore A O-Ring built to an inside diameter of 0.674 in (17.12 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.88 in (22.35 mm). This o-ring remains the most cost-effective sealing element available for pressurized assemblies.

Buna-N (Nitrile) is specified here for strong abrasion and tear resistance, reliable performance in both static and dynamic service. Expect good resistance to many alcohols, water, and propane and butane. Published continuous service range is -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where strong acids or polar solvents are present.

Maintenance and OEM teams specify it across fluid power, automotive, and agricultural equipment.
