1/4 inch NPT staging check valve
This 1/4 NPT is designed to thread into the top bulkhead where either the vent is removed or where a staging port has been provided. It is a 3000 psi rated valve and requires that the top motor is vented out the top bulkhead. The use of a 1/4 NPT close nipple and press lock fitting to connect to second stage are also required. This is designed for faster fills on larger motors and may require a 1/8 X 1/4 bushing to connect to the staging press lock fitting.
