This Tefen metric agricultural 90-degree elbow is made of black polypropylene and has a barbed connection on one end and a male BSPT threaded connection on the other to connect a tube or a hose to a female BSPT threaded connection at an angle. The barbed connection creates a tight seal on a tube or hose, and the male British Standard Pipe Taper (BSPT) threaded end connects with a female BSPT threaded connection, creating a tighter seal than straight threads. This fitting has an integral hex nut for tightening the fitting by using a wrench. This elbow is made of polypropylene for dimensional stability, resistance to most chemicals, and ability to withstand sterilization. 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 40 to 195 degrees F (4 to 90 degrees C), subject to application. This elbow is suitable for connecting LDPE (low density polyethylene) agricultural pipes, Class 2.5 and Class 4, and other flexible pipes in agricultural 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. Hose fittings are used in systems such as air compressors, automatic manufacturing operations, aircraft controls, and tire installation in industries including agriculture, mining, road construction, firefighting, and aviation.Tefen Advanced Plastic Solutions manufactures plastic fittings for pneumatic, automation, and irrigation applications. The company, founded in 1970, meets International Organization for Standardization (ISO) standard 9001:2000.
