-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, is metal detectable for HACCP and foreign-body control programs. 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.
