568-159 FKM 75 SQUARE CUT RINGS

Use item SV70159 when a FKM Viton 70A Square Ring is required for static sealing and gland designs that call for a square-cut sealing profile. The item is specified by AS568-159; 4.987 inch (126.67 mm) ID x 0.103 inch (2.62 mm) CS; 5.193 inch (131.9 mm) OD, with 5 inch nominal ID; 3/32 inch nominal CS for cross-reference against common gland and replacement dimensions. The FKM/Viton fluoroelastomer construction supports high-temperature service, fuels, lubricants and many chemical sealing environments. It is with a listed temperature range of -15°F (-26°C) to 400°F (204°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.
