The DAKOTA SOURCING 13303 is a copper tee fitting designed for use in plumbing and HVAC piping systems. It provides a three-way branch connection in a copper tube run, allowing a main line to split or accept a lateral feed. The 13303 features a 1/2-inch outer diameter and a 3/8-inch inner diameter, making it suited for small-diameter copper tubing applications. Licensed plumbers and HVAC technicians are the primary installers of this type of fitting in both new construction and service work.
This copper tee is used in residential and light commercial plumbing, refrigeration, and HVAC piping applications where a branch takeoff is needed in a small-diameter copper line. It is appropriate for situations requiring a reliable, sweat-solderable connection point in a compact run of copper tubing. No specific compatible model numbers or system families were identified in the product data provided.
Designed as an OEM-style replacement or standard-service fitting for small-diameter copper tubing systems with a 1/2-inch outer diameter specification.
Installation of copper tee fittings is typically performed by a licensed plumber or HVAC technician. Shut off water or refrigerant supply and relieve system pressure before beginning work. Use appropriate flux and solder rated for the application, and follow applicable codes including IPC and IFGC guidelines for copper joint preparation and soldering procedure. Allow joints to cool fully before restoring system pressure.
