Copper end feed solder reducing tee with 3 ways for air conditioner plumbing - Three port copper fitting for end feed solder connections, sized for 1/4 inch, 3/8 inch and 1/2 inch piping to suit AC water lines. - Material: copper body for durability, reliability, and corrosion resistance in air conditioning installations. - Size options: ID sizes from 8 to 159 mm, with common sizes including 10 mm and 12.7 mm. - Function and performance: providing smooth transitions between different pipe diameters, reducing turbulence and maintaining efficient water flow in cooling system plumbing. - Compatibility: designed for copper piping in air conditioner systems, suitable for end-feed solder joints. - Installation notes: requires soldering to copper pipes to create a secure, leak-free joint. - Practical use scenarios: - Branch a main water line to two smaller lines feeding an AC condenser and a valve manifold. - Retrofit an existing copper run by replacing a tee to restore proper flow and branching. - Install in tight spaces where a compact three-way connection is needed to route supply or condensate lines in indoor/outdoor units.
