568-118 FKM 75 SQUARE CUT RINGS

This FKM Viton 70A Square Ring, item SV70118, is designed for buyers who need a clear specification match for static sealing and gland designs that call for a square-cut sealing profile. The item is specified by AS568-118; 0.862 inch (21.89 mm) ID x 0.103 inch (2.62 mm) CS; 1.068 inch (27.13 mm) OD, with 7/8 inch nominal ID; 3/32 inch nominal CS for cross-reference against common gland and replacement dimensions. Its FKM/Viton fluoroelastomer material provides 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. 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.
