High Purity Two-Stage Regulator
The Harris KH1125 is a two-stage high-purity gas regulator designed for breathing air applications. It mounts directly to a cylinder and uses a knob for outlet pressure control. The unit delivers a maximum outlet pressure of 125 psig from a maximum inlet pressure of 350 psig.
Cylinder Mount With NGO Inlet
This regulator connects to a cylinder through a female 0.885"-14 NGO right-hand inlet thread. The outlet is a female 1/8 inch tube fitting with right-hand threads. The two-stage design provides consistent outlet pressure as cylinder pressure drops, reducing the need for frequent readjustment during use.
Replaces Single-Stage Breathing Air Units
Upgrading from a single-stage regulator is worthwhile when a steady outlet pressure is required throughout the cylinder life without manual intervention. It is not suited for gas types other than breathing air or for inlet pressures exceeding 350 psig. Buyers needing different outlet connections or higher flow capacity should verify compatibility before purchase.

Questions about this item
What is the highest inlet pressure the KH1125 regulator can accept before it must be replaced?
The maximum inlet pressure is 350 psig; sustained use above that limit will exceed the design rating of the two-stage body.
How much heat or noise does the regulator produce during continuous all-day operation?
The regulator has no moving parts that generate heat or sound, so it remains silent and at ambient temperature under steady flow.
Which cylinder fitting must I already have for the 0.885"-14 NGO inlet to connect?
You need a breathing-air cylinder with a right-hand female 0.885"-14 NGO valve outlet to match the regulator inlet.
