Reliable Connection for Split Air Conditioner Systems
Mini split air conditioning systems rely on a stable connection between the indoor and outdoor units.
The PE insulated copper pipe (mini split line set) plays a key role in transporting refrigerant while maintaining thermal efficiency and protecting the copper tube.
At XLBAODI, we manufacture PE insulated copper pipes designed specifically for HVAC installations, providing reliable performance, consistent quality, and flexible OEM solutions for global partners.

A mini split system uses refrigerant lines to transfer heat between the indoor and outdoor units.
These lines must ensure:
• Efficient refrigerant flow
• Minimal energy loss
• Reliable insulation protection
• Long-term durability in different environments
Our PE insulated copper pipes are designed to meet these requirements and support smooth HVAC installation.
Each mini split line set is composed of two essential components:
Inner Layer: Copper Tube
Made from 99.9% pure copper (C1220T / ASTM B280)
High thermal conductivity for efficient heat transfer
Compatible with common refrigerants
Copper tubes are produced according to international HVAC standards including:
• ASTM B280
• EN12735
• AS1571
• JIS H3300 C1220T
Outer Layer: Three-Layer PE Insulation
Our insulation uses a three-layer structure (LDPE + IXPE + PE) designed to provide:
• Excellent thermal insulation
• Moisture resistance
• UV resistance
• Long-term durability
This structure helps reduce energy loss and protects the copper pipe during installation and operation.
✔ Stable thermal insulation performance
Helps maintain refrigerant efficiency and reduce heat loss.
✔ Flexible and installation-friendly
Easy to bend and install during HVAC system setup.
✔ Durable insulation protection
Resistant to moisture, UV exposure, and mechanical wear.
✔ Consistent manufacturing quality
Stable production processes ensure reliable pipe performance.
Many HVAC distributors and brands require customized line sets for different markets.
At XLBAODI, we provide flexible OEM solutions including:
• Customized copper pipe sizes
• Insulation thickness options
• Customized pipe length
• Logo printing on insulation
• OEM packaging
• Optional accessories
This allows customers to build their own branded HVAC installation products.
PE insulated copper pipes are widely used in:
• Ductless mini split air conditioners
• Heat pump systems
• Residential air conditioning installations
• Commercial HVAC projects
They are an essential component for reliable and efficient air conditioning systems.
For distributors and HVAC brands, working directly with a manufacturer provides advantages such as:
• Stable product quality
• Flexible customization
• Efficient production planning
• Reliable supply for seasonal demand
With over 20 years of experience, XLBAODI focuses on manufacturing PE insulated copper pipes and supporting HVAC partners worldwide.
