Air Venturi Foster Female to 1/8-Inch BSPP Male Quick-Disconnect Adapter, 5,000 PSI

For those of us in the PCP Airgun Hobby, there's definitely a need for high quality & perfect fitting connectors..Over the years, I've tried several different brands/styles, but, these Air Venturi QD fittings are some of the best!When installing to the hose-end-threads, I have one little trick..Rather than using 'white' thread tape, I use 'yellow thread tape'. [it's better/thicker - used on gas pipe threads]Since doing that years ago [even on high pressure pneumatic air ride auto/cycle suspension, it's worked Great]These fittings thread on flawlessly, connect and disconnect flawlessly, and they've been paired with several different brand male fittings with zero issues at all. I have handfuls of them at this point..Highly Recommended!Sam -

Only weird thing I wish they had explained is what the little screw in the middle is for. After some internet searches, I found the screw is meant to slow air flowing through the fitting. I'm guessing if you fill a small tank from a large higher pressure tank it might give a little extra control of the fill rate, making it easier to avoid overfilling. I use a hand pump, so i removed it without any issues.Fits tightly. Doesn't leak. Looks up to the job.

This foster fitting is of the highest quality. I originally had ordered this item to replace a newly ordered one which came on a Airforce Scuba K valve for filling my Airforce Condor. The K valve was in excellent shape upon arrival, however, the Female foster fitting leaked air furiously, and looked like it was part of a previous return and swapped onto my new unit. I however did not know that the threading on the Air Venturi is different than that of the Airforce Scuba adapter, one is course thread, the other fine thread, Excellent quality , yet, would not fit no matter my effort or wishing it do so. Have initiated the return process and am grateful for that. Again a quality item, yet it will not fit therefore I cannot use the item

Good quality, works well.

Works exactly as advertised! Only problem I encountered, and that's because I'm a newbie and didn't know, was that you have to tighten this down with a wrench, which is why it has a hex shaped shaft.I initially connected it to a mico-hose to use on my Hill MK4 pump, connecting it to my Benjamin Marauder, and air was escaping. I thought it was defective, until I learned online that you need to tighten everything down with a wrench. After I did it worked IMMEDIATELY!!!Funny because I thought it was defective and started a return to AirGunDepot, but after learning it was my mistake I bought another one (for my scuba tank), lol.In short words, it works and I would recommend it.

Works great now but it came with out the internal gasket. I made it work

This is the fitting used on Benjamin a Discover and Marauder guns as well as various CO2 propelled paintball guns. It costs more than many less expensive brass fittings as it's made of steel, and in this case it's money well spent. Brass is acceptable for CO2, which has a vapor pressure of around 900psi at around 72 degrees Farenheit. But PCP guns are typically pressurized to 2600 or 3000psi, and air tanks used to charge them go up to 4500psi. At those kinds of pressures you do not want a fitting that will fail.Incidentally, when attaching this to your Hill or other pump, do NOT use Teflon tape or pipe compound. This connector is designed to work without it, and you'll get a better seal without adding the tape.

Unfortunately the threads were damaged on the one sent to me so i returned it. I do think it’s overpriced, essentially your paying for the brand other products are equally as good.
