Ordered as VQ4249, this is an AS568-249 black Viton® (FKM) 75 Shore A quad profile Quad-Ring with an inside diameter of 4.859 in (123.42 mm), a cross section of 0.139 in (3.53 mm), and an outside diameter of 5.137 in (130.48 mm). The quad-ring seats in a standard o-ring gland while offering improved dynamic performance.
It resists aggressive chemicals, aromatic hydrocarbons, and many acids. That behavior comes from the compound itself: Viton® (FKM) is widely chosen for the industry benchmark where nitrile reaches its thermal limit and outstanding high-temperature capability. The material carries a published service range of -15°F (-26.1°C) to 400°F (204.4°C).
Typical settings include high-temperature process equipment, semiconductor equipment, and chemical processing.
VQ4249 ships individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
