Check Valves

PISCO Check Valves allow air to flow one way and block it in the other, holding pressure or protecting part of a circuit from backflow. They drop into a line on one-touch push-in tube connections, so no tools or thread sealant are needed on the tube side. Use them to hold a cylinder in position, to isolate an accumulator, or to keep exhaust from feeding back into a supply line. Genuine PISCO, available from PISCO USA.
