Buna 70-2.5mmCSx14mmID-Black-Pk100

Ordered as SB-H2.5X14-100, this is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 14 mm (0.551 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 19 mm (0.75 in). The o-ring creates a positive seal at flange, piston and rod interfaces without added hardware. Source specification: 14MMIDX2.5MMCS.

As a material, Buna-N (Nitrile) is known for low compression set under sustained load and the most widely specified general-purpose sealing elastomer. The compound resists greases and lubricants, petroleum-based oils, and propane and butane. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C). Exposure to polar solvents or strong acids will shorten service life.

Typical settings include fluid power, construction equipment, and agricultural equipment.

SB-H2.5X14-100 ships by the bag. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
