A drip pipe fitting is a component used in drip irrigation systems to connect and direct the flow of water. It typically consists of a threaded connector that allows for easy attachment to other components.
When you mention "thread heavy tee," I assume you're referring to a tee fitting with threads on all three ends. A tee fitting is used to create a branch or split in the irrigation system, allowing water to flow in multiple directions. The threaded ends of the tee fitting enable you to connect it securely to other pipes, fittings, or valves.
