TADERUILY 33 Ft Mini Split Line Set
The TADERUILY 33 Ft Mini Split Line Set features high-grade copper tubing designed for mini split air conditioners and heat pump systems. It includes 1/4″ and 1/2″ outside diameter thickened copper pipes with 3/8″ PE insulation, which is effective against leaks and supports high and low pressure operation. This line set is ideal for installations requiring moderate distance between indoor and outdoor units, ensuring reliable refrigerant flow and durability.
findmall 50FT Copper Tubing Hose Extension
The findmall 50FT Extension provides extended capacity with durable copper tubing sized 1/4″ & 3/8″. The thickened insulation cotton protects the copper from heat damage and reduces energy loss. Designed to withstand temperatures up to 80 degrees on the insulation layer, this set is suitable for long-distance installations where protection and flexibility are crucial. The material toughness promotes longer service life for HVAC applications.
Wostore 50Ft Mini Split Line Set
The Wostore 50Ft Mini Split Line Set stands out for its robust copper thickness, with 0.65mm for 1/4″ and 3/8″ pipes, and 0.7mm for the 1/2″ pipe. ASTM B743 compliant, it includes a fire retardant insulation layer with an embossed polyethylene film to resist abrasion and weather exposure. The added UV protection extends the product’s life, while the insulation minimizes noise and energy loss, making it suitable for both residential and commercial HVAC setups.
HOXHA 25 Ft Mini Split Line Set
The HOXHA 25 Ft Mini Split Line Set offers excellent insulation with a triple-layer design including embossed polyethylene, weather-resistant foam, and thick insulating cotton. The copper tubing features increased wall thickness ensuring high-pressure endurance and reliability under varying temperatures. Designed for 9000BTU and similar systems, this line set balances size and performance for smaller to mid-range mini split installations.
ICOOL 25 Ft Mini Split Line Set with Fittings
The ICOOL 25 Ft Mini Split Line Set combines high-quality 0.65mm and 0.7mm thick copper pipes with a triple-layer insulation system. The set is flame retardant (M1 level), corrosion-proof, and capable of enduring temperatures from -40℉ to 248℉, suitable for differing refrigerants. Pre-flared ends with nuts facilitate easy, leak-free installation. This product is durable for HVAC refrigeration and heating equipment.
Buying Guide for Mini Split Long Line Sets
When selecting a mini split long line set, several important factors should be considered to ensure the best fit for your HVAC system:
- Length of Line Set: Choose a line set that matches or exceeds the distance between your indoor and outdoor units to prevent partial runs or extensions.
- Copper Pipe Diameter: Common sizes include 1/4″, 3/8″, and 1/2″. Ensure compatibility with your mini split system’s specifications for refrigerant flow efficiency.
- Copper Wall Thickness: Thicker copper walls (≥0.65mm) enhance durability and resistance to pressure fluctuations and environmental damage.
- Insulation Quality: Insulation like PE foam or thickened cotton reduces heat exchange and protects against moisture, increasing system efficiency and longevity.
- Temperature and Pressure Ratings: Confirm that the line set can safely operate under the expected temperature extremes and pressures of your HVAC system.
- Installation Ease: Pre-flared ends with nuts simplify installation and help maintain leak-free connections for reliable performance.
- Durability Features: Consider UV resistance, flame retardancy, and corrosion protection capabilities if your line set will be exposed to outdoor elements.
- Compatibility with Refrigerants: Verify the line set is suitable for the type of refrigerant your system uses (e.g., R410A, R32).
By comparing these factors alongside your specific system requirements, you can select a mini split long line set that offers optimal performance and long-term reliability.
