Q-117 BUNA 70 Q RING

This Buna-N NBR 70A Quad Ring / X-Ring, item QH70117, is designed for buyers who need a clear specification match for low-friction dynamic sealing, lubricant retention and replacement of standard round O-rings in compatible glands. The item is specified by AS568-117; 0.799 inch (20.29 mm) ID x 0.103 inch (2.62 mm) CS; 1.005 inch (25.53 mm) OD, with 13/16 inch nominal ID; 3/32 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. 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 quad profile provide a practical visual identifier during receiving, stocking and installation. The quad-ring or X-ring profile can provide multiple sealing lips and lubricant-retention benefits in compatible dynamic glands. 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.
