The H2.5X27 is a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 27 mm (1.063 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 32 mm (1.26 in). This o-ring creates a positive seal at flange, piston and rod interfaces without added hardware.
As a material, Buna-N (Nitrile) is valued for reliable performance in both static and dynamic service, the most widely specified general-purpose sealing elastomer. Expect good resistance to greases and lubricants, petroleum-based oils, and hydraulic fluids. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C).
It sees regular use in general industrial maintenance, hydraulic and pneumatic systems, and construction equipment.
Stocked as H2.5X27 and sold individually. Unit weight is approximately 0.57 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.
