568-467 BUNA 70 SQUARE CUT RINGS

Use item SH70467 when a Buna-N NBR 70A Square Ring is required for static sealing and gland designs that call for a square-cut sealing profile. The item is specified by AS568-467; 18.955 inch (481.46 mm) ID x 0.275 inch (6.99 mm) CS; 19.505 inch (495.43 mm) OD, with 19 inch nominal ID; 1/4 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 square profile provide a practical visual identifier during receiving, stocking and installation. The square-cut profile can help fill rectangular glands and provide broad contact for compatible static sealing designs. 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.
