1.25MM CS X 8MM ID BLACK BUNA 70D

APG stocks the H1.25X8, a black Buna-N (Nitrile) 70 Shore A O-Ring supplied with an inside diameter of 8 mm (0.315 in), a cross section of 1.25 mm (0.049 in), and an outside diameter of 10.5 mm (0.41 in). An o-ring provides a reliable static or dynamic seal by deforming into its gland under assembly load.

It resists hydraulic fluids, greases and lubricants, and many alcohols. That behavior comes from the compound itself: Buna-N (Nitrile) is valued for an economical choice for high-volume maintenance programs, reliable performance in both static and dynamic service. Continuous operating temperature is published at -40°F (-40°C) to 250°F (121.1°C).

Maintenance and OEM teams specify it across agricultural equipment, automotive, and fluid power.

Stocked as H1.25X8 and sold individually. Review your operating media and conditions against this specification before installation.
