What this regulator controls
This Victor brass gas regulator manages oxygen flow from a high-pressure cylinder for general-purpose welding tasks. It uses a single-stage design with a CGA-540 inlet and a 9/16 in. -18 M LH outlet. The body is brass with a stainless-steel diaphragm and measures 3.64 in. in diameter.
Pressure delivery and gauge range
The unit delivers an adjustable outlet pressure from 2 to 60 psi while the supply gauge reads up to 4,000 psi. Maximum rated inlet pressure is 3,000 psi. It is listed to UL252 by ETL and carries a California Proposition 65 reproductive-harm warning.
Buyers who need different gas services
This model is specified for oxygen service only; it will not suit fuel-gas or inert-gas applications that require other CGA connections. The single-stage construction also means outlet pressure will vary as the cylinder empties, so users needing constant pressure across the full cylinder should consider a two-stage alternative.

Questions about this item
How do I install the Victor HAWA 0781-3600 regulator on an oxygen cylinder, and which step is often done incorrectly?
Connect the CGA-540 inlet nut to the cylinder valve, then attach the hose to the 9/16 in.-18 M LH outlet; the step often missed is using a proper oxygen-compatible seal and leak-testing at 3,000 psi max inlet pressure before opening the valve fully.
What maintenance or replacement will the Victor HAWA 0781-3600 regulator need over time?
Inspect the stainless-steel diaphragm and brass body seats regularly; replace the unit if the delivery pressure drifts outside the 2 to 60 psi range or if the 4,000 psi supply gauge reads inaccurately.
What is the first limit reached on the Victor HAWA 0781-3600 regulator during sustained high-flow use?
The single-stage design causes delivery pressure to rise as the cylinder empties, so the 60 psi upper delivery limit is typically reached first, requiring frequent manual adjustment to stay within the 2 to 60 psi range.
