SÜA LDB Series Regulators – Light-Duty Precision for Oxygen, Acetylene, and Propane
The SÜA LDB 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 LDB 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 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.

I had a small problem with the oxygen regulator, but their Customer Support was super helpful and the new part arrived almost the next day.Happy I was able to Made it a set with their Propane and Oxygen Adaptors(with a lot of Teflon tape unfortunately, but going to use liquid seal next time) and make it works perfectly with my Smith little torch. No leaks so far

My regulator had started fluttering so I checked to see the repair cost and found this cheaper than repairing my old one. So far it is working fine. It has small gauges like others that fit the small bottles so you will need to mark where the needle should be if you have older eyes like mine.

The propane regulator leaks and doesn't hold pressure and the oxygen goes way too high in pressure when it's being purged. Never had a regulator like either of these

I ordered these SUA oxy acet regulators not knowing what to expect. I'm not a profesional HVAC, but I know that theses don't feel cheap. They are very well constructed and feel heavy duty. My last set sat for so long that the oxy regulator blew the diagram. I was worried that these were going to be subpar. They are not. They feel very durable. They are made in china. They are very affordable. At $ 35 each regulator! That was the cheapest I could find for the model I needed. The big GAS stores wanted 80 for each. These will do for now.

Replacement for potable torch. Came well packaged, fit on small tanks, and worked as intended. No leakages. Seems to be a good product.

This regulator did not work. It does not reduce output pressure, and therefore is unusable. I contacted the company directly by phone and was told that a replacement would be shipped, and that I would receive a confirmation email. I have not received said email. I expect the replacement in the mail today, at my job site, where I cannot produce stock until I receive a functional regulator. My production and custom orders are being affected. I will update if I receive my replacement today.Update: I received my replacement today, less than a week after receiving the defective one, and it seems to be working well. I will test for a week, and update again. I've increased my star rating accordingly.

If you spend some time, you will find Chinese industrial equipment can be well made and an excellent deal, or, all to often, bad stuff. This regulator is one of those items which is well made at a good price. They make several models with placement of the inlet and control knob differences. It is brass or bronze. I use propane as my fuel and adjustment of the regulator is critical to a smooth running torch. This one does the trick.

Worked great in my garage. I might only use my torches 30-40 hours per year. I’m disabled and restore old cars as much as I can on my good days. Couldn’t afford an expensive set so I bought all the pieces on Amazon and saved hundreds. Excellent for my uses. I don’t know if they would hold up in a production shop but for the DIY crowd perfect.
