This Legris 6340 LIQUIfit wye is a polymer push-to-connect fitting. The male wye connects a tube to two tubes running in the same direction. It has push-to-connect tube connections on all three ends. The body of the fitting is made of a polymer containing both petroleum- and plant-based polymers. The non-biodegradable material maintains chemical integrity and durability to friction at hot or cold temperatures. This fitting meets National Sanitation Foundation (NSF) 51, NSF 61 C HOT, Water Regulations Advisory Scheme (WRAS), Food and Drug Administration (FDA), American Chemical Society (ACS), EU regulation 1935/2004/EC, and Restriction of Hazardous Substances (RoHS) technical specifications. This wye 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.
