8mm Quick-Disconnect Plug Adapter, Stainless Steel 1/8" NPT Male Thread PCP Paintball Charging Fittings with Sealing O-Ring

This is exactly what my hpa setup needed. This product seemlessly replaced the male quick connect on my oil and water filter, which allowed me to start my compressor with my air tank open. No need to wait on compressor to equalize to the pressure in the tank before opening the tank. This product takes all the guess work out. It's high quality,a breeze to install and fit my budget. It's air tight with the addition of a couple wraps of Teflon tape.

Really excellent quality, works well.

Simple fix for Airforce Talon air rifle. Did not need thread tape. Used silicone thread lube. Included valve base sealing ring works well, tank holds pressure over days with minimal drop. Appears to be much better quality than Airforce OEM valve.

Definitely worth the money

The fill nipple size was 9.7mm OD. Of course the fill nipple on the Gauntlet SL30 is 9.2mm OD ( outside dimension). The height is short (good thing). Easy to install. Made of quality. Price is what it is. No leakage. Functions as should.

The small oring inside that makes the check valve work doesn't last very long, the the check valve doesn't work. If you have some orings of the right size on hand, and don't mind changing them regularly, then you would be okay. Kind of a pain though.

I have looked at every web site for a replacement air fitting for my Beeman QB Chief 1317 with No luck . After finding the thread Size metric #10-1 meaning metric 10 1 is very fine thread's. Bingo works like a champ all I did Was add a "0" ring above the threads like original to stop a leak.. price quality all top notch.

This one-way, high pressure fitting is just what I needed for topping off my air tanks. I can now open the air tank fill valve without having to to wait until the air compressor pressure matches the tank pressure. No more worries of high pressure air suddenly back flowing to the compressor and causing undue strain to it.
