Acetylene Regulator CGA-520 15 psi
This single-stage brass regulator controls acetylene flow from a CGA-520 cylinder. It delivers outlet pressure up to 15 psi through a 9/16-18 LH B connection. A 2-inch supply gauge reads up to 400 psi maximum inlet pressure. The unit includes a nickel-plated bonnet and filtered seat for clean operation.
Suits general-purpose acetylene welding
Buyers needing higher delivery pressure or a different inlet connection should choose another model. This regulator is limited to 15 psi outlet and CGA-520 cylinder fittings only. It does not support dual-stage regulation or alternative gas services. Builders requiring oxygen or propane regulation need a separate unit.
Delivery pressure fixed at 15 psi
The 15 psi outlet range is the key specification that determines compatibility with your torch and tip selection. Verify that your application operates within this pressure limit before purchase. The single-stage design provides consistent flow for standard welding tasks. Maximum inlet pressure is rated at 400 psi.

Questions about this item
What cylinder valve fitting does the CGA-520 inlet on this regulator connect to?
The CGA-520 inlet threads directly onto a standard acetylene cylinder valve rated for up to 400 psi supply pressure.
Will the 9/16-18 LH outlet thread fit the hose and torch fittings I already use for acetylene?
Yes, the 9/16 in.-18 LH B outlet is the common left-hand thread used on acetylene welding hoses and torch handles.
How can I confirm the regulator is delivering the correct 15 psi working pressure after I install it?
Watch the 2 in. delivery-pressure gauge; the needle should settle at 15 psi when the torch valve is open and gas is flowing.
