Comments:It sure would be nice if this site would provide specs on the part.

This part is 45 cents. Not expensive. But cheapest shipping option to me is almost $12, and probably slow.

After using this part, I reassembled it again using parts at my hardware store. I was able to use a rubber quad-ring to get this to work. I believe it was 3/4 outer diameter. Fits perfectly within the hex nut with no clearance on the outside, and outside the inlet nipple with no clearance on the inside. Perhaps a male or U-Cup shaped O-Ring would work just the same with the ridges pointed toward the regulator and away from the CO2 tank, sealing the gap that allows the nut to slide back over the nipple.

Go to your hardware store and buy one of each for $1 and don't wait for shipping.
Bottom Line:I would not recommend this product.
