XQC Series quick-connect fittings are said to feature an ergonomic grip and convenient release button for ease of use. According to manufacturer Value Plastics, Fort Collins, Colo., (www.valueplastics.com) the fittings include a single-barb design that balances leak-free operation and minimal assembly effort against an increased tubing-pulloff resistance without external clamps or adhesives. O-ring seals provide long life and repeated connect-disconnect cycles. Buna-N O-rings are standard and other seal materials are available on custom order. Integral shutoff valves stop flow at disconnect in one motion when necessary. XQC Series products are manufactured from acetal copolymer resin and interchangeable with many button-type plastic or metal couplings and fittings. They can withstand ethylene oxide and common autoclave sterilization procedures.
