This Spears schedule 40 PVC tee fitting has barbed male inserts on each end, and is suitable for connecting and branching flexible polyethylene tubes. The barbed ends allow a quick connection to flexible tubing. The fitting is T-shaped and has three openings to connect and branch three tubes, two on the main run and one branch at a 90-degree angle from the middle of the tee. Dimensions for tees are represented as A x B x C. “A” and “B” indicate the main run on the fitting, and “C” indicates the branch. The fitting is made of gray PVC (polyvinyl chloride) for chemical and corrosion resistance, high strength, and less weight than fittings made from metal. It is compatible with SIDR-PR (standard inside dimension ratios, pressure rated) flexible polyethylene tubing according to ASTM International standard D2239, or standard D2104 schedule 40 polyethylene tubing. The fitting has a maximum operating temperature of 140 degrees F, meets ASTM International D1784 and D2609 standards for quality assurance, and is certified by National Sanitation Foundation International (NSF) for potable water service. This PVC tee fitting is suitable for connecting flexible polyethylene tubing for a range of liquid transfer 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.Spears Manufacturing produces thermoplastic fittings and valves for fluid, drain, waste, and vent systems. The company, founded in 1969 and headquartered in Sylmar, CA, meets International Organization for Standardization (ISO) standard 9001.
