Q-448 FLUOROELASTOMER 75 Q RING

Use item QV70448 when a FKM Viton 75A Quad Ring / X-Ring is required for low-friction dynamic sealing, lubricant retention and replacement of standard round O-rings in compatible glands. The item is specified by AS568-448; 9.475 inch (240.67 mm) ID x 0.275 inch (6.99 mm) CS; 10.025 inch (254.64 mm) OD, with 9 1/2 inch nominal ID; 1/4 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 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. 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.
