This Weatherhead 1074X6 mini-barb brass bulkhead union has a 0.27" fitting end outside diameter (OD) and is suitable for use in joining 3/8" OD flexible plastic tubing through a bulkhead. The mini-barb ends are push-to-connect and do not require hose clamps or ferrules for use in low-pressure air, coolant, and vacuum applications. The fitting is made of CA360 brass for corrosion resistance, ductility at high temperatures, and low magnetic permeability. A 3/8-24 UNF threaded hex-head nut securely attaches the fitting to a bulkhead. This mini-barb brass bulkhead union is suitable for use in applications such as temperature control circuits, test apparatus, coolant lines, and pneumatic circuits.

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.
