I have never used this brand but wanted to try it with the airbag air lines we bought. These airbags are used in the water purification process. We use them to expand the airbags to pressurize the gasket material with the backing plate to seal the water from large diameter open air ducts just to withstand the pressure (18psi average). This is maintenance support and added security. These faucets offer a professional look, simple plumbing configurations and the finish is still well cared for. I know they are airtight because they submerge in water with no air bubbles escaping under pressure. Like all hose quick disconnects, they snapped together and sealed the first time they were inserted/connected. I haven't tried removing and reusing the seal to prove seal repeatability.
