0558004184 - ESAB 90-Degree Elbow Fitting 5/16 Tube to 1/4 NPT Male

Precision Connection for Industrial Equipment

The ESAB 0558004184 is a specialized 90-degree elbow fitting designed to facilitate secure and reliable connections within industrial welding and plasma cutting systems. Engineered to meet the rigorous standards of ESAB equipment, this component serves as a critical interface between 5/16-inch outer diameter (OD) tubing and 1/4-inch National Pipe Taper (NPT) male ports. In the complex environment of industrial machinery, where space is often at a premium and routing paths can be intricate, the 90-degree geometry of this fitting allows for efficient plumbing of gas or air lines without inducing stress on the tubing or compromising flow characteristics.

Constructed from high-quality materials, this fitting is built to withstand the pressure and environmental conditions typical of welding workshops and manufacturing floors. The 1/4" NPT male thread provides a tapered seal that, when used with appropriate thread sealant or tape, creates a pressure-tight lock resistant to vibration and thermal expansion. On the opposing side, the 5/16" tube connection is precision-machined to grip the tubing securely, preventing blowouts or leaks that could lead to equipment failure, gas wastage, or safety hazards. Whether used for shielding gas delivery in MIG/TIG welders or compressed air supply in plasma cutters, maintaining the integrity of these connections is paramount for process quality.

Using genuine OEM parts like the ESAB 0558004184 ensures that maintenance personnel can perform repairs with confidence. Generic fittings may suffer from slight dimensional variances or inferior metallurgy, leading to cross-threading, poor sealing, or premature corrosion. By selecting the specific part number designated by the manufacturer, operators ensure that the replacement component matches the original engineering specifications exactly. This attention to detail in maintenance helps prolong the lifespan of the equipment, maintains warranty compliance, and ensures that the machine operates at peak efficiency.

Installation of this elbow fitting is straightforward for qualified technicians. The design accommodates standard wrench sizes for tightening, and the robust body resists deformation during installation. It is an essential spare part for maintenance inventories, ensuring that minor plumbing issues can be resolved immediately without significant downtime. From heavy fabrication to precision cutting, every connection counts, and this ESAB elbow fitting delivers the reliability professionals demand.
