Two-Stage Industrial Air Regulator

The Harris KH1030 is a two-stage specialty gas regulator built for industrial air service. It reduces cylinder pressure to a controlled outlet maximum of 125 psig for consistent delivery in welding and fabrication tasks.

CGA 590 Inlet with 0.965-14 Thread

The single specification that decides fit is the CGA 590 inlet connection, sized at 0.965"-14 with a female NGO thread. This matches industrial air cylinders using that exact standard; any other cylinder connection will not seal.

Brass Body with 1/4 NPT Male Outlet

The chrome-plated brass body houses a neoprene diaphragm and feeds a 1/4 inch male NPT outlet. It requires a compatible CGA 590 cylinder and downstream hose or manifold with a 1/4 inch female NPT port to complete the gas circuit.

Questions about this item

What does the 125 psig outlet pressure mean when I connect it to my torch?

It limits the working pressure delivered to the torch to a maximum of 125 psig, so the flame stays steady even as the cylinder empties.

How does the CGA 590 inlet with 0.965-14 threads affect which cylinder I can use?

The CGA 590 nut with 0.965-14 female threads mates only with industrial-air cylinders that have the matching male outlet, preventing cross-connection with other gases.

What clearance do I need for the 1/4 in male NPT outlet when I plumb the hose?

The 1/4 in male NPT outlet accepts a standard 1/4 in female NPT fitting, so allow enough space for the fitting and hose bend radius at the regulator body.
