Dorman 650-005 3/8 In. Black Rubber Vacuum Cap, 10 Pack Universal Fit

So… I bought these after needed to take apart some air tools to clean after they somehow got clogged by a small ant colony (???).. forgot to take a picture. Perfect fit over the fitting to make sure it doesn’t get contaminated in any weird way.

Exactly what I needed. Accurate and complete description was invaluable.

I use them to make “feet” for trivets that I make out of 3/8” square or round steel. They keep the trivet from scratching up the kitchen cabinets they’re used on.

My fault however, the picture for this shows more than 1 cap. This is actually 1 cap and not worth the $6 charge. If you need more than 1 I suggest looking somewhere else.
