High-Purity Copper Tubing – Engineered for Performance

99.9% Pure Copper Meets ASTM Standards

Manufactured using C12200 copper, this tubing complies with ASTM B280 standards, ensuring:

• Excellent thermal conductivity

• Strong corrosion resistance

• Long service life

This makes it ideal for professional HVAC and refrigeration systems.

High Pressure Resistance for Modern Refrigerants

With a pressure rating of 2100–7000 PSI, this copper tubing easily supports high-pressure refrigerants such as R410A and R32.

That means safer operation and long-term reliability—even under demanding conditions.

Advanced Insulation Technology for Maximum Efficiency

UV-Resistant & Weatherproof Insulation

The insulation is made from high-density polypropylene or rubber, offering:

• UV resistance for outdoor use

• Flame retardancy (UL94 compliant)

• Temperature resistance from -40℃ to 120℃

Triple-Layer Insulation Structure

• Outer Layer: UV-resistant PE film

• Middle Layer: IXPE foam for thermal insulation

• Inner Layer: Closed-cell airtight structure

This multi-layer design ensures consistent insulation performance and long-term durability.

Moisture & Condensation Protection

The closed-cell insulation structure acts as both:

• Thermal insulation layer

• Moisture barrier

This prevents condensation and protects walls, ceilings, and equipment.

99.9% Pure Copper

Black Rubber Insulated Pipe

Plastic Cap

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.

Key Benefits of 100 ft Insulated Copper Tubing

Ideal for Long Distance HVAC Installations

The 100 ft length is perfect for:

• Large residential projects

• Commercial HVAC systems

• Rooftop and multi-floor installations

Fewer joints = fewer leak points = higher reliability.

Improve Energy Efficiency & System Performance

Pre-insulated tubing minimizes heat exchange, allowing your HVAC system to operate more efficiently and reduce energy consumption.

Faster Installation & Lower Labor Cost

Factory-applied insulation eliminates additional wrapping, saving time and labor during installation.

Durable, Corrosion-Resistant & Long-Lasting

Copper’s natural corrosion resistance ensures a lifespan of 15–20 years or more when properly installed.

HVAC Applications – Wide System Compatibility

This insulated copper tubing is suitable for:

• Mini split air conditioners

• Heat pump systems

• Central air conditioning systems

• VRF/VRV systems

Typically used for 4.5–6 ton HVAC systems (54,000–72,000 BTU).
