Description
Old Part Numbers: CTD3812-P1-SU3, 1238TAMC
3/8" Compression x 1/2" MPT with 1/8" FPT side port with cold start valve.
NOTE: For Emglo units, order this for the AM78/AM780 HC4V tank style only without serial# prefix "A".
If the small unloader (bleeder) valve on or under your switch leaks constantly AFTER the unit shuts off, replace this part. The check valve is a one-way valve that prevents air from backfeeding from the air tank.
