568-139 BUNA 70 DURO WHITE FDA

Use item H70FDA139 when a Buna-N NBR 70A FDA Metal-Detectable O-Ring is required for food processing, packaging, washdown and detectable sealing applications where material selection is critical. The item is specified by AS568-139; 2.175 inch (55.25 mm) ID x 0.103 inch (2.62 mm) CS; 2.381 inch (60.48 mm) OD, with 2 3/16 inch nominal ID; 3/32 inch nominal CS for cross-reference against common gland and replacement dimensions. The Buna-N nitrile (NBR) construction supports oil, grease, fuel and general hydraulic fluid resistance in common industrial equipment. It is with a listed temperature range of -40°F (-40°C) to 250°F (121°C), which can help narrow material selection for heat, cold or process exposure. The white color and round profile provide a practical visual identifier during receiving, stocking and installation. This category is commonly specified for processing environments, packaging equipment and washdown areas where seal identification matters. The each-unit format supports precise replacement, kitting, resale and job-specific purchasing. This product belongs to FDA and metal-detectable material options for food processing and detectable sealing applications. Important product identifiers include O-rings, replacement seals, fluid sealing, material compatibility and dimensional fit. It supports customer comparison, distributor cataloging and specification-based selection without relying on pricing, availability or shipping claims.
