Drain cock valve a mysterious elusive beast

My dad gave me his UST air compressor but somewhere prior to arrival at my house the drain cock value disappeared.


I'm currently on hold for Pep Boys (where he purchased) but I'm not hopeful they will have one. However, hope does spring eternal. I came across this forum while waiting and listening to some really weird music on Pep Boys hold.

I see Home Depot has a "universal" valve so I will drop in and see if it will work.

I too tried to call UST and after many rings got a message that the mailbox is full so no message could be left. At this point even if I left a message I'm pretty certain no one would respond. Does that smell of scam somehow?

I have UST Power System Plus Model # 1106C

Patti, is it missing? or you can't find it?

They are almost always at the bottom of the tank, and sometimes they get sheared off.

If that's the case, then most any 1/4 inch NPT valve will work, so long as it doesn't hit the floor.

IIRC, the HD valve will certainly work, but if the "full flow ball valve" won't hit the floor, I'd use one of those, maybe with an elbow if it's a bit long. That valve has both male and female threads, so any 1/4 inch elbow will work, the ball valve doesn't care which end is which...
