SÜA LDB Series Regulators – Light-Duty Precision for Oxygen, Acetylene, and Propane
The SÜA LDP Series Regulators are designed for light-duty applications, providing reliable gas control for welding, cutting, brazing, and heating. Featuring a rear connector design, these regulators ensure a secure fit and efficient gas flow, making them ideal for workshops, hobbyists, and small-scale fabrication projects.
Built with high-quality brass construction, the LDP Series offers precise dual gas gauges for accurate pressure readings and an ergonomic control knob for easy adjustments. Available for Oxygen, Acetylene, and Propane, these regulators deliver smooth operation, safety, and durability in every task.
Oxygen Regulator
A regulator with a CGA-540 fitting is designed to connect to American oxygen tanks that use the CGA-540 valve. These tanks are commonly used in industrial and welding applications. The CGA-540 connection is standard for high-pressure oxygen cylinders, typically containing oxygen at pressures up to 3,000 PSI or more. It is NOT compatible with low-pressure or non-oxygen gas cylinders.
Acetylene Regulator
A CGA-200 regulator fits small MC acetylene tanks used in welding and cutting applications. It is NOT compatible with other acetylene or gas cylinders.
Propane Regulator
The CGA-510 standard is used for high-pressure acetylene and propane tanks, including welding, industrial heating, and propane grill-style tanks. It is NOT compatible with small MC acetylene tanks or disposable propane canisters.

They probably okay never used them yet but they're awful small compared to my old ones

These fit my Smith Little Torch perfectly. I like the valve knobs much better than the T style turners.

I very very rarely review a product, and to be honest this is less of a product review and more of a seller review. When you get one that is above the rest of this day in age I feel like they should be shouted from the roof top. The regulators came lickety split. The O2 turned out to be bad and caused some downstream issues as well. I reached out to the seller and within hours they had resolved things and I had a new regulator on the way. I cannot say how refreshing it was to deal with a seller who took things serious and had a desire to take care of the seller. Regulators work wonderfully and I am very happy.

At $35, this was acceptable. i'm satisfied, i think. though i like the dual gauge setup, i tend to prefer the simpler regulator for the air-acetylene torch. seems like the throughput is more consistent. that's not to say this is a bad item. i think it may pair better with the oxygen. if i head down that route, i will likely buy the matching regulator.

Fit my small welder perfectly and the knob is much smoother than my old one. I cranked it up to see how it felt it was smooth and steady

Pretty good regulator vary durable unit I use it outside and it holds up vary well this is the second one I've purchased the only reason I had to buy a replacement is because my tanks fell on top of the regulator the only bad thing about it is the adjustment is vary sensitive

This gauge is heavy , solid, and appears to be of very high quality, particularly for the price, and works flawlessly for me. I needed a gauge quickly to replace one I had that was the wrong size for an MC acetylene bottle. This gauge attaches directly to an MC bottle and threaded to my hose set without any problem. This item was delivered in less than 24 hours and I am very pleased.

Replaced old gauges on small torch set that were wore out. I did have to purchase a $6.50 thread adapter for the acetylene line to the regulator from a local welding gear store. One of the gauge bodies was a little loose too. Just had to tighten up the two Philips head mounting screws on the back. May go back later with some thread locker if they work out again. Much needed, cheap, happy customer.
