🔒 Compressed Air HPA Tank Nipple Covers by Captain O-Ring - 10 Pack with Bonus Microfiber Cloth Review

For just one pair of O-rings, think $0.25 each. But they do a very good job and my inflation valve on my high pressure air tank stays clean even when I'm in a dusty mess.

Installs on the tank filler nipples. They dangle a bit, hopefully they fit better around the nipples. They remain firmly connected at the base. Cheap price so don't expect anything too crazy.

very fast delivery! Like most reviewers, I would have preferred a slimmer fit. I still gave 5 stars because they are good quality and do their job. Fill the pacifier.

They fit HPA quick release nipples, too loose for use in wet, foggy, rainy, sleet etc. If the room is too windy and dusty I don't think these caps will keep the nipple clean. IMHO I think these caps need to be slightly larger and slightly smaller in diameter to seal the teat well and keep it clean.

Good price. Neat product. The only reason these sleeves don't get a 5 star rating is because they don't stay on the nipples of my paintball gun air tanks. They fit very poorly and easily detach from the nipple. The retaining ring is also a bit large and does not hold the cap securely to the tank. But for the price it's better than nothing!

A simple little cap with lanyard. This will prevent debris from getting on the QD connector of your PCP air gun or air tanks. You can spend the bulk of a $10 bill on a fancy metal cap, or get 10 caps cheaper. If you lose the special cap that is part of the rifle's appearance, you can use one of these small caps until a new cap arrives. It pays to have a package handy.
