The item is specified by AS568-449; 9.975 inch (253.37 mm) ID x 0.275 inch (6.99 mm) CS; 10.525 inch (267.34 mm) OD, with 10 inch nominal ID; 1/4 inch nominal CS for cross-reference against common gland and replacement dimensions. Its Fluorosilicone material provides fuel and oil resistance paired with low-temperature flexibility for specialty sealing service. It is with a listed temperature range of -80°F (-62.2°C) to 350°F (177°C), which can help narrow material selection for heat, cold or process exposure.

The each-unit format supports precise replacement, kitting, resale and job-specific purchasing. Common purchasing identifiers for this product include the material name, O-ring type, dimensional size, hardness and intended sealing application. Those attributes make the item easier to compare for maintenance, OEM production, MRO replacement and reseller catalog use.
