Copper tees are used for diverting, merging, and branch direction-changing conveyance of media in pipeline systems. By structure, they are divided into equal-diameter, reducing, and 45° diagonal tees; by connection method, they are divided into four types: threaded, press-fit, welded, and union. We use H59/H62 high-precision brass and TU2 high-purity copper (corresponding to C11000/C12200) as raw materials, processed through precision forging, one-piece forming, CNC precision turning, polishing and passivation, and other processes, with dense and uniform pipe walls and precise thread engagement. The copper material itself has antibacterial, rust-proof, high and low temperature resistant, and thermal expansion and contraction resistant properties, and can withstand a temperature range of -40℃ to 180℃ for a long time, adapting to various media such as cold water, hot water, purified water, gas, refrigerant, hydraulic oil, and clean gases. The products are manufactured in accordance with standards such as GB/T11618, ASTM B280, EN1254, and NSF61. Finished products undergo acid pickling passivation and anti-oxidation treatment, and are low-lead and environmentally friendly. Regular specifications support sample submission for inspection and engineering replacement parts; non-standard sizes, materials, and thread systems can be customized according to drawings or samples.
Overview
Copper tees are three-way pipe fittings used in pipeline systems for medium diversion, merging, and branch direction change. We provide two major categories: brass tees and copper tees. The products use H59/H62 high-precision brass or TU2 high-purity copper as raw materials, and are processed through precision forging, one-piece molding, CNC precision turning, polishing and passivation, and other processes. The pipe wall is dense and uniform, and the threads engage precisely. By structure, they are divided into equal-diameter, reducing, and 45° diagonal tees. By connection method, they are divided into threaded, press-fit, welded, and union types, covering the full diameter range of DN6–DN100 and compatible with 2-point to 1-inch plumbing specifications. Copper material naturally has antibacterial, rust-proof, high- and low-temperature resistant, and thermal expansion and contraction resistant properties. It can withstand a long-term temperature range of -40°C to 180°C and is suitable for transporting multiple media such as cold water, hot water, purified water, gas, refrigerant, hydraulic oil, and clean gases. The products are produced in accordance with standards such as GB/T11618, ASTM B280, EN1254, and NSF61. Finished products undergo acid pickling passivation and anti-oxidation treatment, and are low-lead and environmentally friendly.
Key Features
The core value of copper tees lies in the antibacterial, rust-proof, temperature-resistant, and pressure-resistant properties of the copper material itself, as well as the sealing reliability brought by precision machining. Compared with carbon steel and cast iron pipe fittings, copper tees will not rust and clog, and will not contaminate the medium due to corrosion. They are suitable for scenarios with requirements for pipeline cleanliness, such as purified water, gas, and medical clean applications. We use a forged one-piece molding process, so the pipe wall is dense with no sand holes or air pores. The threads are CNC precision turned for precise engagement, reducing leakage risks. The material's temperature resistance range covers -40°C to 180°C, and it can adapt to alternating hot and cold, humid, and pipeline vibration working conditions. The connection methods are flexible. For conventional household and engineering pipelines, threaded or union types can be selected. For central air conditioning clean pipelines, welded or press-fit types can be selected. The entire series can be made with low-lead or lead-free treatment, meeting drinking water and food-grade cleanliness standards.
Applications
Copper tees are suitable for occasions with requirements for pipeline cleanliness, sealing performance, and temperature resistance. In household water purification scenarios, they are used for residential tap water branches, water heater water distribution, and whole-house purified water pipeline systems. The antibacterial properties of copper ions help ensure water cleanliness. In HVAC scenarios, they are used for central air conditioning circulating water, floor heating manifolds, and building hot and cold circulating pipe networks, adapting to alternating hot and cold working conditions. In gas transportation scenarios, they are used for civil and commercial low-pressure gas branch pipelines, requiring explosion-proof and seepage-proof performance and oxidation resistance. In medical clean scenarios, they are used for hospital sterile water supply and clean gas pipelines, requiring compliance with food-grade cleanliness standards and no metal precipitation. In industrial precision scenarios, they are used for refrigeration refrigerant pipelines, hydraulic equipment oil circuits, and precision instrument fluid branch systems, requiring pressure resistance, fatigue resistance, and durable sealing. In kitchen and bathroom electromechanical scenarios, they are used for commercial building water supply and drainage and pipelines in alternating dry and wet environments.

Purchasing & Delivery
Copper tees are precision clean pipe fittings. Their surfaces are easily scratched, and threads are easily bumped. We use packaging solutions that are dust-proof, scratch-proof, rust-proof, and pollution-proof. All threaded ports are individually fitted with custom plastic thread protectors. Each single product is individually wrapped with anti-static pearl cotton and moisture-proof oil paper. Small and medium specifications are packed separately in thickened hard cartons with built-in desiccant and layered isolation cotton. Large precision thickened styles are individually foam-shaped and sealed. Full-container export shipments use fumigation-free solid wood pallets, reinforced with high-strength steel straps and fully wrapped with stretch film, which can withstand ocean shipping salt spray and humid environments. English shipping marks, specification parameters, batch numbers, and customer LOGOs can be customized.

FAQ
What advantages do copper tees have compared with iron pipe fittings?
Copper tees have characteristics such as natural antibacterial water purification, rust prevention, no pipeline blockage, good sealing performance, and resistance to high and low temperatures. Iron pipe fittings are prone to rust and blockage, and corrosion will contaminate the medium, while copper tees do not produce iron rust contamination, have higher cleanliness, and have a longer service life, making them suitable for high-end water purification, HVAC, gas, and precision pipeline scenarios.
How to choose between brass tees and copper tees?
For conventional plumbing, gas, and hydraulic working conditions, the more cost-effective H59/H62 brass tees can be selected; for high-end refrigeration, high-pressure circulation, and high-purity clean pipelines, it is recommended to use TU2 copper tees with stronger ductility and corrosion resistance. For specific selection, please contact us, and we will assist in confirming according to your working conditions and medium.
How to choose the connection method for copper tees?
For conventional pipelines in home decoration and engineering projects, threaded or union connections can be selected, offering flexible disassembly and assembly and convenient maintenance; for clean pipelines of central air conditioning, welding or press fitting can be selected, providing more stable sealing performance and stronger integrity. 45° oblique tees have lower resistance and are suitable for pipelines with flow requirements. For specific connection methods, please contact us for confirmation.
Do copper tees comply with drinking water standards?
All products can undergo low-lead and lead-free treatment, are produced in accordance with relevant NSF61 water purification certification standards, and the finished products undergo acid pickling passivation and anti-oxidation treatment. They are low-lead and environmentally friendly, with no medium precipitation, and are suitable for water purification and drinking water pipelines. For specific certification documents, please contact us for confirmation.
