Buna 70-2.5mmCSx17mmID-Black-Pk100

Part number SB-H2.5X17-100 is a black Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 17 mm (0.669 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 22 mm (0.87 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces. Source specification: 17MMIDX2.5MMCS.

The compound resists greases and lubricants, propane and butane, and many alcohols. That behavior comes from the compound itself: Buna-N (Nitrile) is known for low compression set under sustained load, strong abrasion and tear resistance. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). Applications involving ketones or ozone and direct sunlight call for a different compound.

Typical settings include construction equipment, fluid power, and general industrial maintenance.

SB-H2.5X17-100 ships by the bag. Review your operating media and conditions against this specification before installation. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
