*568-221 EPR 70 NSF ORINGS

Use item E70NSF221 when an EPDM 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 AS568-221; 1.421 inch (36.09 mm) ID x 0.139 inch (3.53 mm) CS; 1.699 inch (43.15 mm) OD, with 1 7/16 inch nominal ID; 1/8 inch nominal CS for cross-reference against common gland and replacement dimensions. The EPDM (EPR) construction supports water, steam, weathering and outdoor sealing applications where petroleum oil exposure is not the primary requirement. It is with a listed temperature range of -65°F (-53.9°C) to 300°F (149°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. 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.
