950391 - ESAB Brass Hex Nipple - 1/8 NPT Male x 1/4 Hose Barb

Precision Brass Connection for Industrial Gas Systems

The ESAB 950391 Hex Nipple is a critical component for professionals maintaining or assembling gas distribution systems. In the world of industrial welding and cutting, the integrity of every connection point dictates the safety and efficiency of the entire operation. This fitting is designed to bridge the gap between rigid equipment ports and flexible delivery hoses, specifically converting a 1/8-inch National Pipe Thread (NPT) female port into a connection point for a 1/4-inch Inner Diameter (ID) hose.

Manufactured from high-quality brass, this nipple offers superior resistance to corrosion and oxidation, which is vital when dealing with various shielding gases or environmental conditions found in workshops. The brass construction also ensures that the threads are robust enough to withstand tightening torque without stripping, yet soft enough to create a tight metal-to-metal seal when engaged with a corresponding female fitting. The hexagonal body section provides a convenient gripping surface for wrenches, allowing technicians to secure the fitting firmly without damaging the barb or the threads.

This component is particularly useful in manifold assemblies, regulator outlets, or custom machine setups where standard connections need to be adapted to flexible lines. The barbed end is precision-engineered to grip the inner liner of standard 1/4-inch welding hoses. When secured with a proper hose clamp or crimp ferrule, it creates a gas-tight seal that prevents leaks, ensuring that expensive shielding gas reaches the weld pool rather than dissipating into the atmosphere. Whether you are setting up a new TIG station or repairing an existing MIG gas line, the ESAB 950391 provides the reliability professional gas engineers demand.

Proper gas flow is the lifeline of any arc welding process. Using inferior fittings can lead to turbulence, leaks, or contamination of the gas stream. By choosing genuine ESAB brass fittings, you ensure compatibility and performance consistency across your equipment. This simple yet essential part helps maintain the high standards required for code-quality welding and safe workshop operations.
