METAL DETECTABLE BUNA 70 568-333

Use item H70MD333 when a Buna-N NBR 70A 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 AS568-333; 2.475 inch (62.87 mm) ID x 0.21 inch (5.33 mm) CS; 2.895 inch (73.53 mm) OD, with 2 1/2 inch nominal ID; 3/16 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 black 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. Its metal-detectable formulation supports detectable sealing applications where lost-part risk management is part of the specification. 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.
