Leader Check Valve Adapter - 5/16" - Clear

Proven Check Valve technology effectively eliminates the back flow of sap from the tubing system. Sap that leaves the hole during short sap runs cannot be pulled back by the tree as it freezes. Contaminated sap from the tubing system is prevented from being pulled back into trees, extending the sugaring season and substantially increasing sap production.
