Q-337 FLUOROELASTOMER 75 Q RING

This FKM Viton 75A Quad Ring / X-Ring, item QV70337, is designed for buyers who need a clear specification match for low-friction dynamic sealing, lubricant retention and replacement of standard round O-rings in compatible glands. The item is specified by AS568-337; 2.975 inch (75.57 mm) ID x 0.21 inch (5.33 mm) CS; 3.395 inch (86.23 mm) OD, with 3 inch nominal ID; 3/16 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 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. 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.
