HOXHA 13 Ft Mini Split Line Set Extension
This 13 ft line set uses high-quality copper tubing with wall thicknesses of 0.65mm for 1/4″ and 3/8″ tubes, and 0.7mm for 1/2″ tubing, which provides enhanced durability and strength under pressure. The line set is wrapped with a triple-layer insulation system comprising an embossed polyethylene film, weather-resistant foam, and thickened insulating cotton. This construction helps resist extreme temperature variations and protects against environmental damage. The sizing is universal for most mini split air conditioners, making it a versatile choice for many installations.
findmall 50FT Air Conditioning Tubing Hose Extension
Perfect for longer runs, this 50 ft copper tubing set features a 1/4″ and 3/8″ diameter, suitable for most mini split systems. The tubing is made of copper, valued for its ductility, corrosion resistance, and long lifespan. A thickened insulation cotton surrounds the copper tubes, which helps reduce heat exchange and protects the tubes from physical damage. The insulation is designed to withstand temperatures up to 80 degrees, aligning well with HVAC requirements.
TADERUILY 33 Ft Mini Split Line Set Copper Pipe Extension
This 33 ft copper coil line set is engineered for ductless mini split air conditioners and heat pumps. It features twin lines of 1/4″ and 3/8″ outside diameters that boast high and low-pressure resistance without leaks. The tubing is insulated with PE thickened material, which helps maintain energy efficiency by reducing thermal losses and protecting the refrigerant. The unit comes with nuts for secure and easy installation.
TADERUILY 25 Ft Mini Split Line Set Copper Tubing Extension
This 25 ft line set is suitable for medium-length extension requirements, featuring 1/4″ and 1/2″ outside diameter copper tubes. It is constructed to withstand high pressures and designed for use in mini split air conditioners and heat pump systems. The copper tubing is insulated with thickened PE foam, which enhances energy efficiency and protects the system from temperature fluctuations. It includes fittings that ease the installation process.
HANSUM 25FT Mini Split Drain Hose with Weather Resistant Cover
This 25 ft drain hose is designed to handle the condensate drainage from mini split air conditioners and heat pumps effectively. It fits units with a 5/8 inch internal diameter outlet. The hose features a built-in carbon layer that makes it resistant to all weather conditions, suitable for both indoor and outdoor use. Its flexibility allows for easy connection and adjustment as needed in HVAC systems.
Buying Guide For Mini Split Extension Lines
When selecting extension lines for mini split air conditioners, here are critical factors to consider:
- Length Requirements: Measure the distance between your indoor and outdoor units carefully. Extension lengths vary widely, so pick one that fits your installation without being excessively long, which could reduce system efficiency.
- Copper Tubing Size: Extensions typically come in paired sizes such as 1/4″ & 3/8″ or 1/4″ & 1/2″. Check your unit’s specifications to match the tubing diameter precisely to ensure system compatibility and avoid leaks.
- Wall Thickness: Thicker copper walls provide enhanced durability and resistance to pressure. Look for tubing with at least 0.6mm thickness for better longevity.
- Insulation Quality: High-quality thermal insulation reduces heat loss and protects refrigerant lines from external elements. Options like triple-layer insulating cotton or PE thickened foam are preferred for their weather resistance and energy-saving benefits.
- Fittings and Installation: Pre-flared ends with nuts facilitate a secure and leak-proof connection. Ensure the set you choose includes these accessories or that they are compatible with your HVAC components.
- Environmental Resistance: If the extension lines or drain hoses are routed outdoors, look for weatherproof and UV-resistant materials to prevent damage over time.
- Drain Hose Compatibility: For condensate drainage, select hoses that fit the diameter of your AC drain port and provide adequate length and flexibility, with durable weather-resistant layering.
A well-chosen mini split extension line reduces maintenance needs, maximizes system efficiency, and ensures a reliable HVAC setup. Assessing your installation specifics and system requirements carefully will guide you to the best product.
