whereas the manual configuration needs to be checked and drained by hand periodically

As an added benefit our safety valves also come standard with a manually activated pull-ring that allows you to verify the safety valve is operational and can effectively relieve pressure when needed

Check Valves Configuration:1/8" NPT (M) to 1/8" NPT (F) (O.D. 14mm) whereas the manual configuration needsCheck valves are one way pneumatic valves designed to be installed in the leader hose or exhaust port of the compressor. They keep the high air pressure away from the compressor head, preventing high amperage starts and extending the life of the compressor. *Torque spec for 1 8" NPT is 10 11 lb ft *Torque spec for 1 4" and 3 8" NPT is 12 15 lb ft
