Portle Injection Tip 0.5 

Portle Injection Tip for conifers and hard-to-treat hardwoods. Portle Tips have multiple “ports,” ports, or openings, along the end of the tip which deliver chemical numerous points in the inner active layers of conifers, and allows you to inject more chemical at each injection site when desired. A check valve in the base of each tip keeps chemical in the tree until it is absorbed. Portle Tips have also proven beneficial when injecting tough-barked hardwoods such as hackberry and hickory, thick-barked hardwoods such as elm and eucalyptus, or when the bark of any type tree becomes harder to penetrate when making late summer or fall injections. The short Portle Tip works well for injecting Sycamore and London Plane trees that can be difficult to inject with the Wedgle Tip.
