5/16 (.312) SILICONE ORING CORD 70 DURO

APG stocks the 0286312, a red Silicone 70 Shore A O-Ring Cord Stock measuring a cross section of 0.312 in (8 mm). An o-ring cord stock supports field repair of oversized or non-standard sealing grooves without a special tooling charge.

The compound resists ozone and UV exposure, extreme heat and cold, and weathering. That behavior comes from the compound itself: Silicone offers physiological inertness and low toxicity, flexibility that holds at very low temperatures. Exposure to concentrated acids or abrasive dynamic service will shorten service life.

You will find this material specified across ovens and heated equipment, food and beverage processing, and pharmaceutical manufacturing.

Stocked as 0286312 and sold by the foot. As always, verify media compatibility and operating conditions against the requirements of your specific application. APG can cross-reference from an existing part number, a drawing or a physical sample if this size is not an exact match.
