Universal 8mm Quick-Disconnect Plug Adapter 1/8" BSPP Female Thread Paintball Fittings with Sealing O-Ring

I have a Hatsan AT-44 and this worked just fine with my fill probe. I tried both offerings from iorman as they had slightly different descriptions but they are identical and work with my Hatsan probe. Both came with a feeling seal but I used a wrap of Teflon tape in addition just to be sure. I snugged them down with wrenches (snug not super powered torqued as the probe is made of brass and will crack of torqued to strongly). Zero issues with both my Chinese compressors (Davvy and Yong Hen) and my additional moisture trap. These are as well made as the brand name (that claims to be made in the US but mine came in a bag that said assembled in the US with foreign components) and I actually prefer these as they fit in my probe case a little better (they are a bit shorter).

This adapter is the same as the Air Venturi adapter. I have a Hatsan Flashpup QE .22 and it fits the fill probe perfectly. You have to insert the little white seal into the adapter. Put about five raps of Teflon tape on the fill probe threads. Works perfect and doesn’t leak. The price is about half of the other brand. I am very happy with my purchase and would buy it again.

This was the fitting I needed. It is high-quality and was easy to get from Amazon.

I had to grind the tip down a little as it was just a little too long (maybe 1/16th). It would not fully insert into a Foster QD until I ground it a little. I compared it to other fittings I have and the tip was a little longer than others. I would still purchase this item again. Would have been 5 stars otherwise.

I used this adapter to connect the fill probe for my Weihrauch HW110ST PCP air rifle to a eBay hand pump with the standard foster quick disconnect. It works great and for $10 it’s worth buying one for every fill probe that you have.
