Victor 0781-3642 Regulator Overview
The Victor 0781-3642 is a single-stage gas regulator built for carbon dioxide cylinders with a CGA-320 inlet. It delivers an adjustable outlet pressure from 0 to 40 psi through a 5/8 in.-18 F RH connection. A brass body and neoprene diaphragm handle a maximum inlet pressure of 4,000 psi. The 2 in. supply gauge reads up to 3,000 psi for clear monitoring.
Build Integration Requirements
This regulator threads directly onto a CO₂ cylinder fitted with a CGA-320 valve, so no adapter is required for that gas service. The 5/8 in.-18 outlet accepts standard RH hose fittings used in many welding and beverage setups. Its 3.6 in. body diameter keeps the profile compact on the cylinder valve. Meeting ASTM G175, CGA E-4, ELT and UL252 standards, it fits regulated workflows without extra certification steps.
Ideal Users and Limitations
Welders and technicians who need precise low-pressure CO₂ delivery up to 40 psi will find the single-stage design straightforward to set and operate. Buyers requiring higher outlet pressures or multi-stage stability for critical processes should look at other models. The regulator is restricted to carbon dioxide service, so it cannot be used with argon, oxygen or mixed gases. California Proposition 65 warnings apply due to listed chemicals.

Questions about this item
What is the maximum inlet pressure the Victor 0781-3642 regulator can handle before the safety relief activates?
The regulator is rated for a maximum inlet pressure of 4,000 psi, and the supply gauge reads up to 3,000 psi.
How much heat does the brass body and neoprene diaphragm generate during continuous CO₂ flow at 40 psi?
The single-stage brass body with neoprene diaphragm does not generate measurable heat during normal operation; ambient temperature rise is negligible.
Which cylinder valve and hose fitting must I already have to connect this CGA-320 regulator?
You need a cylinder with a CGA-320 valve outlet and a hose or torch fitted with a 5/8 in.-18 RH female connection.
