Compressed Air Bubble Manifold Valve with relief. This valve has a 1/2" Male NPT thread which screws into the tank. (Note: 1/2" threads measure about 3/4" in diameter, if needed these threads can be reduced or enlarged with a reducer.) This valve is great for a replacement of an existing valve and also works great if you're making an air storage tank out of a compressor tank.

This valve is equipped with a 1/4" Female NPT port for an air hose as well as a 1/8" Female NPT port for an air gauge, and a Schrader tire fill valve on the side (as shown) for filling the air bubble. The red knob connected to this valve allows you to easily turn on / off the air flow to the air hose. This manifold features a 130 PSI safety relief valve also known as a pop off.
