APG stocks the H2.5X110, a black Buna-N (Nitrile) 70 Shore A O-Ring with an inside diameter of 110 mm (4.331 in), a cross section of 2.5 mm (0.098 in), and an outside diameter of 115 mm (4.53 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.
As a material, Buna-N (Nitrile) is valued for the most widely specified general-purpose sealing elastomer and low compression set under sustained load. The material holds up against petroleum-based oils, greases and lubricants, and many alcohols. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. It is not the right choice where ozone and direct sunlight or automotive brake fluid are present.
Maintenance and OEM teams specify it across hydraulic and pneumatic systems, automotive, and fluid power.
Order part number H2.5X110, sold individually. Unit weight is approximately 2.1188 g. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
