-120 WHITE BUNA 70D FDA O-RING

H70FDA120 is an AS568-120 white Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 0.987 in (25.07 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 1.193 in (30.3 mm). In service, this o-ring compresses into its gland to block fluid or gas migration across a joint.

Buna-N (Nitrile) is widely chosen for strong abrasion and tear resistance, reliable performance in both static and dynamic service. This material stands up to many alcohols, greases and lubricants, and petroleum-based oils. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Exposure to strong acids or ketones will shorten service life.

This o-ring meets FDA requirements for food contact under 21 CFR 177.2600. Typical settings include general industrial maintenance, fluid power, and agricultural equipment.

Stocked as H70FDA120 and sold individually. Unit weight is approximately 0.62 g. As always, verify media compatibility and operating conditions against the requirements of your specific application.
