I tried using car body filler (Bondo, Cuz) and was surprised to find out that stuff didn't seal very well. I covered the top and bottom of the Bondo plug with some JB weld which solved most of my problems. I also tried some clear epoxy by another manufacturer but it feels brittle, I'll probably chis...

I did notice an odd delay between the time I pulled the blow gun trigger and when the valve actually vented...I guess this is due to the length of hose connecting ...

bought similar valve...but leaks, any suggestions?

I bought and modded a 2" Nelson valve. I yanked out the flow control and put 1/4 fitting in its place. There is a medal rod that passed through the diaphram from the flow control that i discarded. I plugged the small hole, the solenoid was removed and plugged, and a small port with a tiny o-ring tha...
