indoor and outdoor units of split air conditioners, mini-splits, heat pumps, and centralized ducted A/C systems.

Key Features:

Dual-tube design (liquid + suction lines) 

— ensures stable refrigerant flow through the system.

High-quality copper + aluminum construction 

— copper provides excellent thermal conductivity & corrosion resistance; aluminum helps reduce weight and production cost.

Pre-insulated tubing 

— reduces thermal loss, prevents condensation, and enhances energy efficiency.

Wide size and configuration options 

— available in multiple diameters (e.g. 1/4″, 3/8″, 1/2″ etc.) and lengths to match different AC capacities and installation requirements.

Durable & reliable performance 

— engineered for long-term use in HVAC and refrigeration systems, withstand varying temperatures and pressures.


Applications

Suitable for ductless mini-split systems, split air conditioners, heat pumps, and centralized ducted HVAC systems. 

Whether for residential installations or commercial HVAC projects, it provides a reliable connection between indoor and outdoor units.
