950263 - Brass Hex Hose Nipple 1/4" NPT Male x 3/16" ID (A-112)

ESAB 950263 Brass Hex Nipple (A-112) Overview

The ESAB 950263 is a precision-engineered brass hex nipple designed to facilitate secure connections in gas welding and cutting systems. Identified by the industry-standard part number A-112, this fitting serves as a critical interface between rigid piping or regulator outlets and flexible welding hoses. The unit features a 1/4-inch National Pipe Thread (NPT) Male connection on one end and a barbed stem designed for 3/16-inch Inner Diameter (I.D.) hoses on the other.

Manufactured from high-quality brass, this component offers superior resistance to corrosion and mechanical wear, making it suitable for the demanding environments found in industrial fabrication shops and field sites. The inclusion of a hexagonal body section distinguishes this nipple from standard round stems, allowing technicians to apply torque using a standard wrench for a tight, leak-free seal against the NPT port. This design feature is particularly beneficial when installing the fitting into manifolds, regulators, or torch handles where a secure mechanical lock is essential for safety.

The 3/16-inch hose barb is machined to provide a snug fit for standard welding hoses. When used in conjunction with an appropriate ferrule or hose clamp (sold separately), it ensures a high-integrity seal that prevents gas leaks even under working pressures. This fitting is an essential inventory item for maintenance, repair, and operations (MRO) professionals who frequently repair damaged hose ends or fabricate custom-length gas lines for specific oxy-fuel or inert gas applications.

Whether you are setting up a new gas distribution manifold or performing routine maintenance on welding equipment, the ESAB 950263 (A-112) provides the reliability and compatibility required for professional results. Its adherence to standard sizing ensures interoperability with a wide range of welding equipment brands and components.
