Harris 301AR-58010 Argon Flow Gauge Regulator Kit

SKU CH-XJ5G-MQJGQ

Single-stage flow gauge regulator kit delivers argon at up to 60 scfh and 60 psig from cylinders rated to 3,000 psig

  • Main materialHAWA
  • Product typeFlow Gauge
  • Single-stage design delivers consistent argon flow up to 60 scfh
  • 3,000 psig maximum inlet pressure handles high-pressure cylinders safely
  • 60 psig maximum outlet pressure protects downstream equipment from over-pressurisation
  • .965 in.-14 NGO female inlet connects directly to standard argon cylinders
  • Includes hose kit for immediate argon welding setup

Argon Flow Gauge Regulator Kit

The Harris 301AR-58010 is a single-stage flow gauge regulator and hose kit designed for argon shielding gas. It mounts directly to a cylinder with a female 0.965-14 NGO right-hand inlet connection and delivers a maximum outlet pressure of 60 psig.

Included hose and outlet fitting

The kit supplies a hose that terminates in a female 5/8 UNF outlet connection, allowing a direct link to compatible welding equipment. This bundled hose removes the need to source a separate argon-rated line and ensures the connection matches the regulator’s 60 scfh maximum flow capacity.

Suited for argon TIG and MIG setups

Welders who need a ready-to-use argon regulator with an integrated hose for cylinder mounting will find this kit convenient. Buyers requiring a different gas type, a two-stage design, or a higher flow rate than 60 scfh should look at alternative regulators.

Questions about this item

How often will the single-stage flow gauge regulator need recalibration or diaphragm replacement under normal argon use?

The single-stage design delivers a steady 60 psig outlet pressure up to the 60 scfh argon flow limit; recalibration or diaphragm service is only required if outlet pressure drifts or the gauge reads inconsistently after extended cylinder changes.

What is the first limit reached when running the argon flow gauge regulator continuously at high flow?

The 60 scfh maximum argon flow rate is the primary limit; exceeding it will drop outlet pressure below the 60 psig set point and starve the weld shield.

How much heat and noise does the brass regulator body produce when flowing argon all day in a fabrication shop?

The all-metal body stays near ambient temperature because expanding argon absorbs heat, and the unit has no moving parts that generate audible noise during continuous operation.
