-007 WHITE BUNA 70D FDA O-RING

H70FDA007 is an AS568-007 white Buna-N (Nitrile) 70 Shore A O-Ring measuring an inside diameter of 0.145 in (3.68 mm), a cross section of 0.07 in (1.78 mm), and an outside diameter of 0.285 in (7.24 mm). In service, this o-ring seats in a machined groove and forms a leak-tight barrier when compressed between two mating surfaces.

Buna-N (Nitrile) is valued for an economical choice for high-volume maintenance programs and low compression set under sustained load. It resists hydraulic fluids, many alcohols, and petroleum-based oils. Rated temperature range runs from -40°F (-40°C) to 250°F (121.1°C) in continuous service. Applications involving automotive brake fluid or polar solvents call for a different compound.

This o-ring meets FDA requirements for food contact under 21 CFR 177.2600. It sees regular use in hydraulic and pneumatic systems, construction equipment, and general industrial maintenance.

Order part number H70FDA007, sold individually. Unit weight is approximately 0.056 g. Application requirements vary, so validate compatibility with your process conditions prior to installation.
