This Tefen industrial 90-degree elbow hose adapter is made of gray nylon 6/6 and has a barbed connection on one end and a male NPT threaded connection on the other to connect a tube or a hose to a female NPT threaded connection at a 90-degree angle. This adapter (also called a connector) is made of nylon 6/6 for lightweight, strength, and resistance to corrosion from most chemicals and solvents. The barbed connection creates a tight seal on a tube or hose when secured with a Tefen snap clip (not included), and the male National Pipe Taper (NPT) threaded end connects with a female NPT threaded connection, creating a tighter seal than straight threads. This fitting has an integral hex nut for tightening the fitting by using a wrench. The maximum operating pressure for this fitting is 200 pounds per square inch (psi) (14 bar) at 68 degrees F (20 degrees C) in a temperature range of -5 to +230 degrees F (-20 to +110 degrees C), subject to application. This male elbow hose adapter is suitable for connecting plastic, rubber, or soft PVC (polyvinyl chloride) hoses in industrial and domestic applications.Hose fittings connect, control, change the direction of, and terminate the flow in piping and hose systems. They are made of brass, stainless steel, galvanized steel, and other materials that resist corrosion, pressure, and wear. Hose fittings have various types of connections, including threaded, barbed, push-to-connect, dry disconnect, and others including those based on internationally-accepted specifications.
