Q-042 FLUOROELASTOMER 75 Q RING

Item QV70042 is a FKM Viton 75A Quad Ring / X-Ring built for low-friction dynamic sealing, lubricant retention and replacement of standard round O-rings in compatible glands. The item is specified by AS568-042; 3.239 inch (82.27 mm) ID x 0.07 inch (1.78 mm) CS; 3.379 inch (85.83 mm) OD, with 3 1/4 inch nominal ID; 1/16 inch nominal CS for cross-reference against common gland and replacement dimensions. The FKM/Viton fluoroelastomer compound is selected for 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. Key selection details include material, hardness, product type, cross-section, inside diameter, outside diameter and application. These specification details help customers and resellers compare the part by performance requirements rather than brand name alone.
