Victor Gas Regulator 0781-3641
The Victor Gas Regulator 0781-3641 is a single-stage brass regulator designed for argon shielding gas. It connects to a cylinder via a CGA 580 inlet and delivers pressure from 0 to 40 psi through a 5/8 in.-18 F RH outlet. A 2 in supply gauge reads up to 3,000 psi.
Build integration and clearance
The regulator mounts directly on an argon cylinder and requires a compatible hose with a 5/8 in.-18 RH fitting to reach the welder. Its brass body and neoprene diaphragm handle a maximum inlet pressure of 4,000 psi. The 3.6 in body diameter fits standard cylinder valves without adapters.
Upgrade context and limits
This unit replaces a worn or missing single-stage argon regulator on existing welding setups. It suits fabricators who need a 0 to 40 psi delivery range for MIG or TIG work. Buyers needing dual-stage pressure stability or a different gas service should select another model.

Questions about this item
Will the single-stage design hold a steady 40 psi delivery when the cylinder drops below 3,000 psi?
Single-stage regulators follow cylinder pressure, so delivery pressure rises as supply pressure falls; the gauge reads up to 3,000 psi supply and 40 psi delivery.
How hot or noisy does the brass body get during continuous argon flow?
The brass body and neoprene diaphragm run at ambient temperature with no moving parts, so the regulator adds no heat or noise.
Which cylinder valve and hose fitting must I already have to connect this 0781-3641 unit?
You need a cylinder with a CGA 580 outlet and a hose with a 5/8 in.-18 RH inlet to match the regulator connections.
