3MM CS X 35MM ID BLACK BUNA 70D

APG stocks the H3X35, a black Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 35 mm (1.378 in), a cross section of 3 mm (0.118 in), and an outside diameter of 41 mm (1.61 in). An o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.

Buna-N (Nitrile) is specified here for low compression set under sustained load, strong abrasion and tear resistance. Expect good resistance to greases and lubricants, hydraulic fluids, and petroleum-based oils. The material carries a published service range of -40°F (-40°C) to 250°F (121.1°C). It is not the right choice where polar solvents or strong acids are present.

Common environments for this compound include automotive, agricultural equipment, and construction equipment.

H3X35 ships individually. Unit weight is approximately 1.056 g. Check the compound against your process media, pressure and temperature before committing to a design. APG supports cross-referencing from drawings, samples and competitor numbers when a listed size is not an exact fit.
