Leader Barbed 5/16 Tees have a special, ultra-aggressive barb design that locks the 5/16 lateral line tubing on securely, so as to eliminate leaks. The fitting is molded to be strong and durable, to last for years as a permanent installation in your maple sugar woods. The interior diameter of  Leader 5/16 plastic tees are the largest in the maple sugaring industry, reducing restrictions and the chance of that fittings will be plugged with ice or bacteria. To ease installation of these tees, we recommend use of a tubing tool.
 
TEE WITH CUP: Designed for use with the Tree Saver 5/16" Diameter spouts, or other spouts that require a 5/16" diameter hole to be drilled in the maple tree. The cup is a sturdier sealing system for these smaller diameter spouts.
 
TEE WITH PLUG: Works with our Stubby Spout and with our 5/16" tubing.
