Harris 3100211 Flowmeter Regulator Kit

The Harris 3100211 is a flowmeter regulator and hose kit built for argon and carbon dioxide shielding gases. It mounts directly to a gas cylinder and is intended for welders who need a combined flow metering and pressure regulation unit for MIG or TIG processes.

Sustained flow regulation and pressure handling

The regulator manages a maximum inlet pressure of 4 000 psig and delivers a controlled outlet pressure up to 3 000 psig through a right-hand threaded 0.965 In. -14 NGO inlet and a 5/8 In. -18 UNF female outlet. This arrangement maintains consistent gas delivery during extended welding runs without pressure spikes.

Argon and CO2 compatibility with cylinder mounting

The kit is specified only for argon and carbon dioxide gas types and uses a cylinder mounting style. It does not support other shielding gas mixes or alternative inlet connections, so buyers using different gases or thread standards will need a different regulator.

Questions about this item

How much heat or noise does the Harris 3100211 regulator produce when running all day?

The regulator has no moving parts or fan, so it generates no measurable heat or noise during continuous operation.

What existing cylinder and hose fittings are required to connect the 0.965-14 NGO inlet and 5/8-18 UNF outlet?

You need an Argon or CO2 cylinder with a 0.965-14 right-hand female NGO valve and a welding hose or torch fitted with a 5/8-18 female UNF connector.

Will the 4,000 psig maximum inlet pressure work safely with older cylinders rated at lower service pressures?

Yes, the regulator controls outlet pressure up to 3,000 psig regardless of cylinder age, provided the cylinder valve matches the 0.965-14 NGO thread.
