Copper twin tube Tubolit Duosplit 1/4 -1/2" Bs1 d0 0.8/0.8 mm pre-insulated for air conditioning systems in a coil of 25m length /25m/ DZC-061288/E25

Pre-insulated copper pipe for air conditioning systems – reliability and efficiency

The Tubolit Duosplit 1/4 - 1/2" double copper pipe is a ready-made solution for installers of air conditioning and refrigeration systems. By combining two pipe sizes (1/4" and 1/2") in a single design, it simplifies installation and reduces the number of connections, which translates to time savings and minimizing the risk of leaks. The product is supplied in a coil with a length of 25 meters, making it easy to adapt to specific installation needs.

Construction and properties

The pipe is designed for high performance and durability. Made of copper with a wall thickness of 0.8 mm, it provides resistance to corrosion and high working pressures. A key element is the pre-insulation with 9 mm thick polyethylene foam, which minimizes energy losses and prevents condensation. This translates to more efficient operation of the air conditioning system and lower operating costs. In addition, the outer layer of plastic in white protects the insulation from mechanical damage and UV radiation.

Safety and compliance with standards

Tubolit Duosplit meets high fire safety standards, achieving a Bs1d0 class. This means that the material is characterized by low flammability, limited smoke emission and the absence of toxic gases during combustion – important aspects in terms of user safety. The pipe is annealed, which increases its plasticity and facilitates forming. The thermal conductivity at 0.036 W/(m·K) guarantees effective thermal insulation. The product is compatible with popular refrigerants such as R-410A, R-407C and R32.
