Premium Quality Propane/Acetylene & Oxygen Regulators. B Size Fitting out.  Set of two regulators. 2 inch gauges. CGA 510 & CGA 540 tank fittings

Included above is a picture of the hoses the regulators will fit, and also a picture of the fittings that attach to the tanks. Hoses are not included. 

Acetylene Regulators are NOT rated for use with propane. This is because of the internal components that can degrade from exposure to propane, which is much more corrosive than acetylene. Only PROPANE rated regulators should be used for propane. The components are made from special materials that do not degrade from exposure to propane. Propane regulators can also be used with acetylene, but not the other way around. 

Thanks very much.
