TADERUILY 33 Ft Mini Split Line Set Extension
This 33 Ft copper tube extension offers leak-free performance at both high and low pressure twin lines. Designed specifically for mini split air conditioners, it features 1/4″ and 1/2″ outer diameter copper tubes with a PE thickened insulating layer. Its copper coil line set construction ensures durability and compatibility with most ductless mini split systems and heat pumps, making it a reliable choice for HVAC maintenance and upgrades.
HOXHA 13 Ft Mini Split Copper Tubing Pipe Extension
The HOXHA line set extension stands out with its thickened copper walls — 0.65mm for 1/4″ and 3/8″ tubes, and 0.7mm for 1/2″ tubes. It utilizes a fire retardant insulation layer shielded by a triple-layer design: embossed polyethylene film, weather-resistant foam, and thickened insulating cotton. This ensures excellent thermal protection while extending line durability. The standard 1/4″ & 3/8″ sizes fit most mini split units, especially systems up to 9000 BTU.
TADERUILY 25 Ft Mini Split Line Set for AC & Heating
This 25 ft twin line set features leak-proof high and low-pressure copper tubing specifically made for mini split air conditioners. The lines have a 1/4″ (6mm) and 1/2″ (12mm) outer diameter and are covered with a thick PE insulated coating to protect against environmental damage. It’s suited for ductless AC and heat pump systems requiring line extensions to ensure proper refrigerant flow and system efficiency.
findmall 50 Ft Air Conditioning Copper Tubing Hose Extension
The findmall model offers an extended length of 50 feet, made with quality copper tubing that ensures durability and resistance against corrosion. Its thickened insulation cotton reduces damage risks to the internal copper and maintains refrigerant temperature stability. Note that the insulation layer is rated up to 80 degrees Celsius. The hoses have diameters of 1/4 and 3/8 inches, fitting a variety of mini split setups with an emphasis on toughness and longevity.
TADERUILY 100 Ft Copper Pipes Replacement Line Set
This 100-foot copper line set is designed for large distance mini split installations. With 1/4″ and 3/8″ outer diameter copper tubes, it provides robust protection against leaks even under high or low pressure. The PE thick insulation safeguards the pipes from weather and temperature fluctuations. Its quality construction is perfect for HVAC professionals or DIY enthusiasts needing extensive copper tubing extensions for ductless mini split air conditioning systems.
Buying Guide for Mini Split Line Set Extensions
Length And Compatibility
Choose the extension length based on the required distance between your indoor and outdoor units. Common lengths range from 10 feet to 100 feet. Verify the copper tube diameters to match your mini split system’s specifications, usually 1/4″, 3/8″, or 1/2″.
Copper Tube Thickness
Thicker copper tubing walls provide better durability and resistance to leaks and damage. Tubes with thickness from 0.6mm to 0.7mm offer reliable strength and are suitable for household mini split systems.
Insulation Quality
Proper insulation prevents energy loss and protects the copper tubing from environmental damage. Look for materials such as PE thickened insulation or multi-layer protection including foam and weather-resistant layers. Check the insulation’s temperature rating to ensure it withstands your climate.
Leak Proof Design And Included Accessories
Ensure the line set is leak-proof with tested high and low-pressure tolerance. Many packages come with pre-flared nuts which simplify installation and provide secure connections with minimal risk of leaks.
Application and Capacity
Confirm the extension’s compatibility with your mini split’s BTU rating. Models suitable for 9000 BTU or higher ensure proper refrigerant flow and system efficiency without strain on your HVAC system.
Durability And Weather Resistance
Copper tubing should be corrosion-resistant and cushioned adequately to withstand sunlight, temperature shifts, and physical wear. Choose line sets with robust outer insulation that can endure the conditions of your installation environment.
