Brass air regulator 5706
The Astro Pneumatic 5706 is a brass-bodied air regulator designed for garage and shop compressed-air systems. It accepts a 1/4" NPT inlet and outlet, letting technicians set line pressure between 90 and 140 PSI for pneumatic tools and equipment.
Sustained pressure control
The regulator maintains the chosen pressure continuously while air flows, rather than only during brief actuation. Brass construction resists corrosion from moisture in the supply line, so the adjustment stays repeatable over long shifts without drift caused by internal rust or scale.
Replaces worn or missing regulators
This unit fits any 1/4" NPT port where a regulator has failed, been removed, or was never installed. The jump is worth it when an existing valve leaks, cannot reach 140 PSI, or lacks the brass body needed for durability in humid shop air.

Questions about this item
Does the brass body of the 5706 regulator get hot or make noise when it runs all day at 140 PSI?
The 5706 is a passive brass regulator with no moving motor or fan, so it generates no operational noise and negligible heat at any pressure up to 140 PSI.
What fittings or hose do I need to connect the 1/4" NPT ports on the 5706 to my air line?
You need 1/4" NPT male fittings on both the supply hose and the tool hose to thread directly into the inlet and outlet ports of the 5706.
Will the 1/4" NPT threads on the 5706 mate with the older 1/4" NPT couplers already on my shop compressor?
Yes, the 5706 uses standard 1/4" NPT threads on both ports, matching the same thread form used on legacy shop compressors and couplers.
