• Ideal for split AC, mini split, and heat pump applications

Whether you’re installing a new HVAC system or replacing existing refrigerant lines, this pipe delivers consistent performance and long-lasting durability.

Technical Specifications – Built for Performance

Premium Copper Tubing

• Material: 99.9% pure seamless copper

• Diameter: 1/2″ (liquid) & 3/4″ (suction)

• Length: 100 ft (30.5 m)

• Excellent thermal conductivity for efficient refrigerant circulation

Copper’s proven performance makes it a trusted choice for HVAC refrigerant lines across residential and commercial projects.

Pre-Insulation Benefits

• High-density insulation installed at the factory

• Improved heat retention and reduced condensation

• UV and moisture-resistant outer jacket

• Supports energy-efficient HVAC operation

Pre-insulation ensures faster installation and reduces onsite labor, helping HVAC professionals complete jobs more efficiently.

Features of pipe insulation tubing:

● Pipe Insulation, Material Black Rubber, Temp Range -40 Degrees to 120 Degrees.

● The pipe insulation has a better function of moisture condensation. Insulation material is both the insulation layer and moisture-proof layer.

● There is no need to drop the water vapor permeation protective layer so that it has a better moisture condensation function.

Advantages of Pre-Insulated Copper Pipe

Enhanced Cooling Efficiency

Pre-insulated copper tubing minimizes thermal loss, allowing your air conditioner or heat pump to operate at peak efficiency — especially in high-demand cooling seasons.

Better Moisture Control

The insulation layer helps prevent condensation and moisture build-up on the copper surface, which protects building structures and components.

Easy Installation

Pre-insulated and ready to install — no need for additional insulation materials. This saves time and lowers overall installation costs.

Ideal Applications – Where to Use This Copper Pipe

This 100-ft pre-insulated copper pipe is suitable for:

• Split air conditioners (residential & commercial)

• Heat pump systems

• Mini split installations

• HVAC retrofits and replacements

• Refrigeration projects requiring copper refrigerant lines

Whether used by HVAC technicians or DIY home installers, this pipe provides dependable performance in a wide range of systems.

Installation Tips & Best Practices

To ensure optimal performance and longevity:

1. Measure the required length before cutting.

2. Avoid sharp kinks or bends that could restrict refrigerant flow.

3. Protect cut edges with flaring and sealing to prevent leaks.

4. Ensure consistent insulation coverage for maximum thermal efficiency.

Following these best practices helps maintain system reliability and reduces maintenance costs.
