Q-167 BUNA 70 Q RING

Use item QH70167 when a Buna-N NBR 70A Quad Ring / X-Ring is required for low-friction dynamic sealing, lubricant retention and replacement of standard round O-rings in compatible glands. The item is specified by AS568-167; 6.987 inch (177.47 mm) ID x 0.103 inch (2.62 mm) CS; 7.193 inch (182.7 mm) OD, with 7 inch nominal ID; 3/32 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 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. 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.
