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. Its Buna-N nitrile (NBR) material provides oil, grease, fuel and general hydraulic fluid resistance in common industrial equipment.

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. Common purchasing identifiers for this product include the material name, O-ring type, dimensional size, hardness and intended sealing application.
