This 7/16" plastic spout is shortened for use with spout adapters and the new check valve adapter, in a two piece spout system. The two piece spout systems offer a better system for tapping to limit the effects of bacteria in the tap hole. Ultimately bacteria will seal the tap hole to end the season and with a two piece spout system the tip of the spout that goes in the tree can be changed for a new bacteria free tip each year. By using the new check valve adapter with the stub spout, production can be maximized because sap that has reached the bacteria filled drop line and permanent stubby spout will not flow back into the tap hole to infect the hole and start the closure process prematurely. The stub spout helps to limit the distance that the spout and drop line stick out away from tree so that falling tree limbs and ice are less likely to do damage to the tubing, or pull the spout out of the tree. The Stub Spout is installed into the adapter by pushing it into the cup on the adapter as you turn the fitting a quarter twist. A very light wrist tap with a hammer is rarely needed to finish seating the stubby spout into the adapter if a leak shows during the season.
