This Eaton Weatherhead 1068X4X1 brass mini-barb fitting connects a 1/16" National Pipe Taper (NPT) male connector to 1/4" outside diameter (OD) flexible tubing. The barbed stem creates a tight seal on flexible tubing without the use of hose clamps or ferrules. The fitting is made of CA360 brass for corrosion resistance, ductility at high temperatures, and low magnetic permeability. This mini-barb fitting is suitable for use in low-pressure air or lubrication lines, such as in temperature control circuits or vacuum lines.

Tube fittings are components used for connecting, branching, terminating, and changing the direction of tubing in pneumatic and hydraulic systems. They are made of brass, stainless steel, polybutylene terephthalate (PBT), and other materials that resist corrosion and wear. Tube fittings have various types of connections, including threaded, welded, barbed, and push-to-connect (also called one-touch). Push-to-connect connections do not require tools or sealants. Tube fittings are used in various applications, including machine tools, airplane and truck controls, and automated production lines, among others.

Eaton manufactures electrical, hydraulic, and mechanical power equipment. The company, founded in 1911, is headquartered in Dublin, Ireland.
