-111 WHITE BUNA 70D FDA O-RING

APG stocks the H70FDA111, an AS568-111 white Buna-N (Nitrile) 70 Shore A O-Ring built to an inside diameter of 0.424 in (10.77 mm), a cross section of 0.103 in (2.62 mm), and an outside diameter of 0.63 in (16 mm). An o-ring compresses into its gland to block fluid or gas migration across a joint.

The material holds up against propane and butane, water, and many alcohols. That behavior comes from the compound itself: Buna-N (Nitrile) is widely chosen for the most widely specified general-purpose sealing elastomer and low compression set under sustained load. Service temperature is rated from -40°F (-40°C) through 250°F (121.1°C).

This item meets FDA requirements for food contact under 21 CFR 177.2600. Maintenance and OEM teams specify it across construction equipment, general industrial maintenance, and agricultural equipment.

Reference part number H70FDA111 when ordering; the item is sold individually. Unit weight is approximately 0.302 g and nominal inside diameter is listed as 7/16 inch. Check the compound against your process media, pressure and temperature before committing to a design. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
