Regulator for Industrial Air

The Harris Products Group KH1118 is a two-stage specialty gas regulator built for industrial air service. It connects to a CGA 590 cylinder valve with a 0.965"-14 female inlet thread and delivers gas through a 1/4 inch male NPT outlet.

Two-stage pressure control

The first stage reduces cylinder pressure to an intermediate level while the second stage holds a steady working pressure up to 125 psig. A knob adjusts the outlet setting and the maximum gauge reads 4000 psig. Brass body with chrome plating and a neoprene diaphragm resist corrosion from industrial air.

Simple bench mounting

The regulator threads directly onto the cylinder valve without extra fittings. Users must verify the CGA 590 match and the 0.965"-14 thread form before installation. Leaks typically come from a damaged inlet seat or an overtightened outlet connection. Not for buyers who need a regulator for fuel gases, oxygen or high-purity gas service.

Questions about this item

Which outlet pressure rating suits my application?

The regulator delivers a maximum outlet pressure of 125 psig, set by its two-stage design for steady flow.

What does the 4,000 psig maximum gauge outlet pressure indicate in use?

That figure is the highest pressure the gauge can read; the working outlet is limited to 125 psig by the regulator itself.

Will the CGA 590 inlet with 0.965"-14 thread fit my industrial air cylinder?

Yes, the female NGO inlet uses the standard CGA 590 connection for industrial air cylinders.
