1.6MM CS X 18.1MM ID BLACK BUNA 70D

APG stocks the H1.6X18.1, a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 18.1 mm (0.713 in), a cross section of 1.6 mm (0.063 in), and an outside diameter of 21.3 mm (0.84 in). An o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

The material holds up against water, many alcohols, and greases and lubricants. That behavior comes from the compound itself: Buna-N (Nitrile) delivers strong abrasion and tear resistance, the most widely specified general-purpose sealing elastomer. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service.

Maintenance and OEM teams specify it across hydraulic and pneumatic systems, construction equipment, and automotive.

H1.6X18.1 ships individually. Confirm chemical compatibility, pressure and temperature against your own application requirements before installing.
