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

Reliable Fuel Gas Hose Extension

The Miller 057020 Brass Hose Coupler is an essential fitting for professional welders and fabricators who need to extend the reach of their oxy-fuel equipment. Designed with precision and safety in mind, this coupler features standard .625-18 Left-Hand (LH) threads on both ends, making it compatible with standard B-size fuel gas hoses used for acetylene, propane, and other fuel gases. Whether you are working in a large shop or on a remote job site, having the ability to connect two hoses securely ensures you can reach your work without moving heavy cylinders.

Durable Brass Construction

Manufactured from high-quality brass, this fitting offers excellent resistance to corrosion and wear, which is vital in harsh industrial environments. The material ensures that the threads remain clean and intact even after repeated use, providing a leak-free seal every time. The hexagonal center section allows for easy gripping with a wrench, ensuring you can tighten the connection securely to prevent gas leaks.

Safety and Compatibility

In welding applications, safety is paramount. The use of Left-Hand threads is a standard safety feature for fuel gases to prevent accidental cross-connection with oxygen lines (which use Right-Hand threads). This Miller coupler adheres to these industry standards, ensuring that your setup remains safe and compliant. It is a direct replacement part or accessory for Miller equipment but fits universal B-size hose connections found in most North American welding setups.
