M-type copper tee fittings are named after their shape resembling the letter "M" and are a type of double outlet diversion fittings.
The main pipe forms a certain angle with the two branch pipes (usually 30 ° -60 °), which results in lower fluid resistance and more uniform flow distribution compared to traditional T-shaped tees.
And they are built to ensure the circulatory system of your HVACR project remains robust for decades. When you hold one of our M-fittings, you'll notice the difference immediately. The surface is perfectly smooth to the touch, a testament to the high-quality TP2 copper and the precision dies used in our extrusion process. There’s a satisfying, solid weight to it, speaking to the exacting material standardswe adhere to. Run your finger along the cut end – it's remarkably clean, with no sharp burrs.
This is the result of our commitment to dual-end deburring, a step many manufacturers skip, but one that saves you valuable installation time and protects your hands.
The copper fittings are extruded by TP2 copper tube, the product has no wrinkles and cracks in the curved part, and the cut is smooth.
The product is used for the connection of refrigeration pipelines.
It is a common refrigeration accessory for air conditioners and refrigerators.
It can also be used for the distribution of vapor and liquid gas.
It has a wide range of uses.

Ningbo Hcool Fittings Co., Ltd. customized production for different pipe diameters and application requirements.
If you have technical drawings, target dimensions, or project specifications, we can help evaluate the suitable product structure for your system.
The current page already states that copper pipe diameter can be customized for different demands,and that samples can be supplied for checking.
Customization options may include:
1. OD of main pipe
2. OD of branch pipe
3.Center distance
4. The angle of the branck pipe
5.Material request, like TP2 or T2.
6.Which refrigerant required.
Q: Are these fittings suitable for use with new, high-pressure refrigerants like R32 or R454B?
A: Absolutely. Our ACR Copper M-Fittings are engineered to handle the operating pressures of modern A2L and other common refrigerants. The TP2 copper material and wrinkle-free construction provide the necessary strength and reliability for high-pressure systems, ensuring safe and long-lasting performance.
Q: I need a fitting that isn't a tee, like a 90° elbow or a coupling. Do you have those?
A: Yes, we manufacture a full range of ACR copper fittings. While this page highlights our M-type tees, we produce elbows, couplings, reducers, and end caps in the same high-quality standard. Please contact us with your specific requirements (sizes and quantities) so we can provide the best solution.
Q: What is the difference between M-type tee and T-type tee?
A: The main difference is in the brancking angle and fluid characteristics.
for normal item, lead time will be 10-15 days.
for the customized item, lead time will be 25-35 days.
