This Legris 3889 90-degree elbow, or "ell," is a 316 stainless steel push-to-connect fitting that connects a tube to a female threaded connection at a 90-degree angle. It has a push-to-connect tube connection on one end and male National Pipe Taper (NPT) threads on the other end for connecting to male threaded pipes. The NPT threads create a tighter seal than straight threads. This fitting is made of 316 stainless steel for higher strength and greater corrosion resistance than 304 stainless steel. Type 316 stainless steel is sometimes called "marine-grade stainless steel" due to its resistance to chloride corrosion. The fitting is suitable for handling pressures up to 435 pounds per square inch (psi) (30 bar) and has an operating temperature range of -20 to +120 degrees C (-4 to +248 degrees F). This fitting meets Restriction of Hazardous Substances (RoHS), Food and Drug Administration (FDA), and EU regulation 1935/2004/EC technical specifications. This 90-degree elbow tube fitting is suitable for use in air, water, oil, chemical, and food applications.
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, PBT (polybutylene terephthalate), 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.
