13 Ft Mini Split Line Set By HOXHA
This mini split line set from HOXHA features thickened copper tubing with wall thicknesses of 0.65mm (1/4″ and 3/8″ pipes) and 0.7mm (1/2″ pipe). The copper is protected by a fire-retardant triple-layer insulated cotton including embossed polyethylene film, weather-resistant foam, and thick insulating cotton. The standard 1/4″ and 3/8″ outer diameter pipes fit most mini split AC systems. Its build quality makes it suitable for both air conditioning and heating systems, with excellent pressure and temperature resistance.
NEAGLORY 10 Ft Mini Split Line Set Twin Copper Tubing
NEAGLORY’s line set uses thickened copper tubing known for durability, corrosion resistance, and high thermal conductivity. The tubing surface is wrapped in 3/8 inch thickened double-layer flame retardant insulated cotton, offering waterproofing, thermal insulation, and shock absorption. It supports a broad temperature range from -40 ℉ to 248 ℉ and works with various refrigerants. The pre-flared ends with nuts simplify installation, making it compatible with many mini split air conditioners and heat pumps.
TAUROX 10FT Mini Split Line Set with Thickened PE Insulation
TAUROX offers a 10-foot copper line set with no leaks under high and low pressure conditions. Featuring standard 1/4″ and 3/8″ diameter pipes, this set is ideal for ductless mini splits. The pipes come with pre-flared ends and nuts for quick and hassle-free installation. The 3/8″ thickened PE insulation coil protects the tubing and improves thermal efficiency, compatible with most mini split HVAC units.
TADERUILY 33 Ft Mini Split Line Set Copper Tubing Extension
This extended length 33 ft mini split line set provides flexibility for longer outdoor to indoor unit connections. It supports both 1/4″ and 3/8″ outer diameter copper tubing and is designed to work seamlessly with ductless mini split air conditioners and heat pumps. The set includes nuts for fastening and features tight seals to prevent leaks, making it suitable for installations requiring extended copper tubing lengths.
ICOOL 50 Ft. Mini Split Line Set with Triple-Layer Insulation
The ICOOL line set offers a 50-foot seamless copper tubing solution for long distance mini split installations. The 0.65mm copper wall thickness is certified by ASTM B743 and resists leaks. It is triple insulated with embossed polyethylene film, climate-resistant foam, and thickened insulated cotton. This insulation ensures flame retardancy, corrosion resistance, and durability across temperatures from -40 ℉ to 248 ℉. The set supports multiple refrigerants and includes flared nuts for easy installation.
Buying Guide For Mini Split Copper Line Sets
Selecting the right mini split copper line set requires careful evaluation across multiple factors:
- Pipe Diameter and Length: Common pipe sizes include 1/4″ (high-pressure) and 3/8″ (low-pressure) outer diameters. Choose a length adequate to connect your indoor and outdoor units with some extra for routing flexibility.
- Copper Wall Thickness: Thicker copper tubing (0.65mm or more) resists flattening, corrosion, and leakage under pressure, enhancing durability.
- Insulation Quality: Look for multi-layer insulation including flame retardant materials and weather-resistant foam. This prevents heat loss/gain, improves efficiency, and protects against environmental damage.
- Compatibility: Confirm the line set fits your mini split model and refrigerant type. Pre-flared ends with nuts simplify installation.
- Temperature Range: Choose line sets rated for a wide working temperature range (e.g., -40 ℉ to 248 ℉) to ensure stable operation in varied climates.
- Installation Accessories: Availability of nuts, caps, and wrapping strips helps ensure secure, leak-free connections and easy assembly.
By considering these points, you’ll select a copper line set that maintains system integrity, maximizes efficiency, and lasts through years of operation.
