Single check valves
Pine Brook, N.J.-based John Guest USA’s Single Check Valves are now available in 1/4” O.D. size as well as its existing 3/8” O.D. size. They provide protection against fluid backflow and can be used with most types of fluids. Designed with Super Speedfit technology, the check valves feature the same simplicity as the company’s fittings for providing a fast and secure way of connecting plastic or soft metal tubing without the use of tools. The valves afford the most reliable and cost effective solution to tubing connections.
