568-021 FKM 75 SQUARE CUT RINGS

Use item SV70021 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 AS568-021; 0.926 inch (23.52 mm) ID x 0.07 inch (1.78 mm) CS; 1.066 inch (27.08 mm) OD, with 15/16 inch nominal ID; 1/16 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.
