Protecting California Air Tank?

[Toestr]

What are some good options for protecting tanks from the screws on the tank holder when running a tank California style? Obligatory pic:

Teflon or rubber caps you can get them at any hardware store. “thread, protector,”

This is a very good idea thank you.

Those look like old vacuum caps for carburetors

Pretty much are they are a lot like a rubber dip coating people put on tools. But they should still grab the tank nicely without damaging it.

Might even be able to use a plastydip tool coating put it in a medicine cup and giver it just the tip.

My kp3 has nylon screws in it. They seem to work well enough, and don't kill my tank. Any idea what threads your tank screws are?

[Toestr]

They're #10-24.

Is there enough room for nylon acorn nuts on the end of the screws?

[Toestr]

Probably not.

[Ecapnation]

Get screws with nylon tips!

[Toestr]

Are there nylon tipped thumb screws?

[Ecapnation]

Yup!

I tried the rubber caps. I forgot how little room there is to screw in the thumbscrews. Looks like I'll be using nylon screws.

[Chuck E Ducky]

Ahh I didn’t think of that yeah it’s pretty tight.

Strip of electrical tape on the tank?

[SuperActionMan]

A metal screw tip will likely cut through tape.

I'd probably try brass shim stock just because I have it, but even a section of soda can would probably work. Or maybe some high durometer 1/16-1/8" rubber sheet and non-marring screws.

Another alternative to the plastic-tipped spade thumbscrews is plastic-tipped Allen screws with a knob cap pressed on. Then you have the option of different styles and colors.

If you can cut or stamp a little bit of brass or nylon, you can drop it down the hole and use it as a wedge between the tank and the screw. That'll work pretty well. Just don't forget about it, because they'll drop out when you remove the tank.

If you're careful with a hot glue gun, you could put a small bead on the tip of the screw. It'll probably peel off once you tighten it, but should work fine until you need to remove the tank.
