    Socket-Connect Check Valves for Oil and Fuel

    Insert unthreaded pipe into the socket ends and weld to create a permanent, leak-tight connection. These heavy duty valves can withstand pressures up to 1,975 psi and temperatures up to 800° F. They open to allow flow in one direction and close when flow stops or reverses. A removable cap provides easy access to internal components for maintenance.
