HOXHA 13 Ft Mini Split Line Set Air Conditioning Copper Tubing

The HOXHA 13 ft line set features thickened copper tubing with wall thicknesses of 0.65mm for 1/4″ and 3/8″ pipes, and 0.7mm for 1/2″ pipes. It includes a triple-layer insulation system made of embossed polyethylene film, weather-resistant foam, and thickened insulating cotton, ensuring excellent durability and thermal protection. This line set is compatible with 9000BTU mini split AC systems and built to withstand high pressure and temperature without leaks, making it ideal for air conditioning and heating installations requiring a shorter line set.
TADERUILY 33 Ft Mini Split Copper Tubing Pipe Extension

This 33 ft TADERUILY line set consists of copper tubing sized 1/4″ & 3/8″ and is designed for mini split air conditioners and heat pumps. It is rigorously tested to ensure no leaks under both high and low pressures. The copper coil tubing and thickened PE insulation provide reliable protection and longevity for ductless mini splits requiring longer tubing runs or customizable installations, suited for various HVAC applications.
TAUROX 10 Ft Mini Split Line Set with Pre-Flared Nuts

The TAUROX 10 ft line set features pre-flared 1/4″ and 3/8″ copper tubing ends with nuts included for easy installation. The tubing is insulated with a 3/8″ thick white PE foam layer, protecting against temperature extremes and preventing condensate issues. Suitable for most ductless mini split AC and heat pump systems, it guarantees leak-proof performance with high-quality copper that resists corrosion and pressure damage.
TADERUILY 25 Ft Mini Split Line Set for AC and Heating

This 25 ft TADERUILY copper line set uses 1/4″ and 1/2″ diameter tubing to accommodate higher capacity mini split systems. The line set features thickened PE insulation and copper tubing certified for leak-free function under HVAC pressures. It supports both air conditioning and heat pump functions and is ideal for installations requiring a medium-length copper line set with reliable insulation for minimal heat transfer and energy loss.
findmall 50 Ft Air Conditioning Tubing Hose Extension

The findmall 50 ft line set offers an extended length suitable for long-distance air conditioner installations. Made from copper tubing with a diameter of 1/4″ and 3/8″, this set includes thickened insulation cotton to protect the tubing and improve thermal retention. The insulation maintains a temperature under 80°C to prevent damage, increasing the durability of the line set for HVAC and mini split systems requiring extensive reach.
Buying Guide for Mini Split Copper Line Sets
When purchasing a mini split copper line set, consider these crucial factors to ensure compatibility and performance:
- Copper Tubing Diameter: Match the diameter sizes (typically 1/4″ & 3/8″ or 1/2″) to your mini split system’s specifications for optimal refrigerant flow.
- Length of Line Set: Choose an appropriate length according to the distance between your indoor and outdoor units. Too short or excessively long lines can affect system efficiency.
- Insulation Quality: Look for thickened PE or triple-layer insulated cotton to minimize heat transfer, prevent condensation, and improve durability under different weather conditions.
- Pre-flared Ends and Fittings: Pre-flared fittings simplify installation and help ensure leak-free connections. Nut sizes should match system requirements.
- Copper Wall Thickness: Thicker walls improve resistance to pressure, minimize damage risk, and extend the lifespan of your line set.
- Compliance and Testing: Opt for line sets tested for high and low pressure leaks and made from seamless pure copper for reliability.
- Environmental Durability: UV resistance, flame retardance, and weatherproof insulation help maintain performance regardless of climate or temperature fluctuations.
- Compatibility: Confirm that the line set fits the brand and model of your mini split air conditioner or heat pump system.
Carefully evaluating these features will help you select a mini split copper line set that ensures efficient, safe, and long-lasting operation of your HVAC system.
