057020 - Miller Brass Fuel Gas Hose Coupler 5/8-18 LH

Miller 057020 Brass Hose Coupler Fitting

Upgrade or repair your welding gas distribution system with the Miller 057020 Fitting, Hose Brass Coupler. This component is engineered to facilitate the connection of two fuel gas hoses, effectively extending the length of your line. It is machined with .625-18 Left-Hand (LH) threads, the industry standard for fuel gas connections (often referred to as B-size fittings). This ensures seamless compatibility with a wide range of hoses used for acetylene, propylene, natural gas, and propane.

Industrial Grade Quality

Miller Electric is known for producing top-tier welding components, and this brass coupler is no exception. The solid brass body withstands the rigors of daily use, resisting deformation and stripping. A secure connection is critical when handling flammable gases, and the precision threading on this coupler ensures a tight, gas-tight seal when used with appropriate hose nuts and nipples. It is an indispensable tool for maintenance and repair operations (MRO) where hose length requirements vary by project.

Application and Usage

This coupler is specifically designed for "Left-Hand" threaded connections, indicated by the notch often found on the nuts of compatible hoses. It serves as a bridge between two hoses equipped with standard B-size female nuts. By using this coupler, operators can easily customize their workspace setup, adding length to their torch leads without the expense of purchasing entirely new, longer hoses. Keep this fitting in your toolbox to ensure you are always prepared for jobs requiring extra reach.
