Acetylene Single-Stage Regulator

The Radnor 64003035 is a single-stage acetylene regulator designed for general-purpose welding. It features a brass body rated for heavy-duty applications and uses a CGA 300 inlet connection. The outlet delivers a maximum pressure of 15 psig.

Check Connections and Gas Compatibility

Verify that your acetylene cylinder uses a male 0.825-14 NGO inlet fitting to match the regulator's CGA 300 connection. Ensure your downstream hose or torch accepts a male 9/16-18 UNF outlet. Confirm the system requires single-stage pressure control.

For General Welding and Heavy-Duty Use

This regulator suits welders needing a heavy-duty brass body for acetylene supply at up to 15 psig. It is not for operators who require multi-stage pressure stability or those working with gases other than acetylene. Buyers needing different inlet or outlet thread standards should look elsewhere.

Questions about this item

What fittings and accessories are included with the Radnor 64003035 acetylene regulator?

The regulator body has a male 0.825"-14 NGO inlet and a male 9/16"-18 UNF outlet. Hoses, flashback arrestors and torch handles are sold separately.

How do I choose the right version of this regulator for my acetylene setup?

This single-stage model is rated for heavy-duty general-purpose use with a maximum outlet pressure of 15 psig and a CGA 300 inlet connection. Verify your cylinder valve matches CGA 300 before purchasing.

What does the 15 psig maximum outlet pressure mean when I am welding?

It limits the working pressure delivered to the torch to 15 psig, which is the standard upper range for acetylene cutting and welding tips in general-purpose applications.
