Questions & Answers

Shandon M : Do you need an o-ring to attach this or does this screw in directly without an o-ring?KEN D : YesDUANE S : no the one I received uses pipe thread, no O-ring neededANTHONY W : No "O" Ring required.JAMES S : Don't remember an o-ring. Think I used teflon tape to seal threads.JACK D : No just screws inJ D P : Screws in without O-ring.. These can also be used to rig an inflator for tires by screwing into a (possibly yellow) inflator hose from Walmart or auto parts store. Use teflon tape to keep air from leaking past threads of inflator hose.
MAURICE I : I have the Scubapro Nighthawk BC and the Atomic SS1. I know the Atomic is a bit bigger size than normal. Is what I will need to rinse out the BC?BRIAN F : This is not for rinsing out the BC. It is to connect a power inflator hose and will not work with the SS1. To rinse out your BC, just put water in through the mouth piece and then drain back out.
Christian E : Hi! This one works with the Aqualung Wave BCD Powerline Inflator?William J : It will not replace the fitting on the BCD inflatorPETER S : I use this to connect my air compressor fitting, tire inflator, etc. to my reg.YAN G : I do not believe it would work.
Shopper : Why Did You Choose This?JAY Y : 1/4" = common air compressor fittings out there.JEFF W : Because of the versatility for other non scuba tasks...very handyKEN B : don't remember

Trident Air Tool Adapter Review - $5.95 - Scuba Gear Customer Reviews

This product allows you to adapt many air tools to work off of a tank such as blow guns and tire chucks. Great for that unexpected flat.

SCUBA tank air supply for airbrushing

The 1/4'' NPT threading of this adapter allows you to quick-connect/disconnect a SCUBA first-stage regulator to standard compressed air tools and accessories. I have my adapter threaded into a standard paint tool regulator (0-60 psi output), which in turn feeds my airbrushes. The air left over in my tank after a dive is plenty enough to do a lot of painting, and tank-supplied air is dry and quiet -- perfect for late-night airbrushing.
