11N22 - B-Size Brass Hose Nipple for 3/16 Inch ID Hose

Precision Brass Hose Nipple for Industrial Gas Applications

The Western Enterprises 11N-22 is a high-quality brass hose nipple designed to facilitate secure connections in oxy-fuel welding and cutting systems. Engineered to meet strict industrial standards, this component serves as the critical interface between the flexible welding hose and the threaded nut that connects to regulators, torches, or other manifold equipment. The nipple features a precision-machined barbed stem that is specifically sized for 3/16-inch Inner Diameter (I.D.) hoses, ensuring a tight friction fit that, when properly crimped with a ferrule, withstands the pressures associated with compressed gases.

This particular model utilizes the industry-standard "B-Size" geometry. In the context of compressed gas fittings, B-Size refers to the 5/8"-18 thread standard used on the accompanying nut. While the nipple itself does not have threads, its seating surface is machined to mate perfectly with B-Size regulator outlets and torch inlets, creating a metal-to-metal seal (or metal-to-seat seal) that prevents hazardous gas leaks. The brass construction provides excellent resistance to corrosion, wear, and thermal fluctuation, making it suitable for a wide range of environments from shop floors to field sites.

The 11N-22 is a universal component regarding gas type; it is compatible with both oxygen and fuel gas systems. The distinction between gases is handled by the nut (Right-Hand thread for Oxygen/Inert, Left-Hand thread for Fuel), which slides over this nipple. This versatility makes the 11N-22 an essential stock item for maintenance departments and welding supply cribs, allowing for the rapid repair of damaged hose ends or the fabrication of custom-length hose assemblies without the need for multiple specialized nipples.

Installation requires inserting the barbed end fully into the cut end of a 3/16" welding hose and securing it with a crimp ferrule or a high-quality hose clamp. The smooth finish of the sealing face ensures that the connection to the equipment remains gas-tight, maintaining system integrity and operator safety.
