Harris 425 Series Regulator

The Harris 425 Series is a single-stage cylinder regulator built for medical air service. It delivers outlet pressure from 0 to 200 psig through a CGA 346 inlet and a 9/16-18 UNF male outlet. The brass body carries a chrome-plated finish and a neoprene diaphragm.

Suited for industrial breathing-air systems

This regulator suits facilities that need a compact, single-stage unit for breathing-air cylinders with a CGA 346 connection. It is not intended for multi-gas manifolds, high-flow cutting torches or applications requiring two-stage pressure stability.

Handles 200 psig outlet with 4,000 psig gauge

The gauge reads up to 4,000 psig so operators can monitor cylinder contents at a glance. The single-stage design provides reliable pressure control up to the 200 psig outlet limit; beyond that range a two-stage regulator would be required.

Questions about this item

What cylinder connection does the Harris 425 regulator need to attach to?

It uses a CGA 346 male inlet with a 0.825-14 thread for breathing-air cylinders.

Will the 9/16-18 UNF male outlet fit my existing medical-air hose?

Yes, the outlet is a standard 9/16-18 UNF male thread used on many medical-air hoses.

How do I confirm the regulator is delivering the set pressure after installation?

The 2.75 inch gauge reads 0 to 200 psig; watch the needle settle at your T-handle setting.
