Harris KH1116 Regulator

The Harris KH1116 is a single-stage high-pressure gas regulator built for argon, helium and nitrogen cylinders. It suits welders and technicians who need precise outlet control up to 3,000 psig from a 5,500 psig inlet.

Sustained delivery

Single-stage construction means outlet pressure will rise gradually as the cylinder empties, so operators must monitor and adjust the knob during long runs. The brass body and 99.9999 percent purity rating maintain clean gas flow for critical shielding or purging tasks.

Installation notes

Connect the female NGO inlet (1.045 in.-14) to the cylinder valve and the 1/4 in. female tube fitting to the downstream line; both threads are right-hand. Common issues are cross-threading the inlet nut or forgetting to purge the regulator before opening the cylinder valve.

Questions about this item

How much heat or noise does the KH1116 produce when running all day?

This regulator has no moving parts or electrical components, so it generates no measurable heat or audible noise during continuous operation.

What cylinder valve and outlet fittings must I already have to install the KH1116?

You need a cylinder with a 1.045 in.-14 NGO female inlet and a 1/4 in female tube fitting on the outlet side to connect the regulator.

Will the KH1116 maintain its 99.9999 % purity rating with the older cylinder valve on my existing tank?

The regulator is rated for 99.9999 % gas purity when used with a compatible 1.045 in.-14 NGO cylinder connection and clean gas supply.
