Goodman - 3-5 Ton Copper Line Set - 3/8" x 1 1/8" - 50ft - CT38X50OD-CT118X50OD-6RX048118
The CT38X Copper Line Set Tubing is strong and corrosion-resistant which makes it the leading choice of modern contractors for plumbing, heating and cooling installations in all kinds of residential and commercial buildings. The combination of easy handling, forming and joining permits savings in installation time, material and overall costs. Long-term performance and reliability mean fewer call backs, and that makes copper the ideal cost-effective tubing material.
Features
- Tube Size(s): 3/8 (inch) and 1 1/8 (inch)
- Copper resists corrosion - Excellent resistance to corrosion and scaling assures long, trouble-free service with copper.
- Copper is lightweight - Copper tube does not require the heavy thickness of ferrous or threaded pipe of the same diameter. This means copper costs less to transport, handles more easily and, when installed, takes less space.
- Copper is flexible - Because copper tube can be readily bent and formed, it is frequently possible to eliminate elbows and joints. Smooth bends permit the tube to follow contours and corners of almost any angle. With soft-temper tube, particularly when used for renovation and modernization projects, much less wall and ceiling space is needed.
- Copper is durable - Copper tube is manufactured to well-defined composition standards and marked with permanent identification so you know exactly what it is and who made it. Copper tube is accepted by virtually every plumbing code.
- Copper is easy to join - Copper tube can be joined with capillary fittings. These fittings save material and make smooth, neat, strong, leak-proof joints. No extra thickness or weight is necessary to compensate for material removed by threading.
- Copper is safe - Copper tube will not burn or support combustion and decompose to toxic gases. Therefore, it will not carry fire through floors, walls, or ceilings. Volatile organic compounds are not required for installation.
What our Experts Think
-
Proper Match for Capacity Range
• Sized for 3–5 ton systems, this line set ensures correct refrigerant flow for many mid‑to‑larger residential and light commercial air conditioners and heat pumps.
-
Durable Copper Construction
• Copper tubing offers excellent corrosion resistance, thermal conductivity, and long‑term reliability — important for maintaining efficiency and minimizing service issues.
-
Pre‑Measured 50 ft Length
• A standard 50 ft length provides flexibility for a wide range of install layouts without excessive field welding or joint issues.
-
Correct Diameter Pairing
• The 3/8″ (liquid) and 1‑1/8″ (suction) tubing sizes are matched to typical refrigerant flow needs of the specified tonnage, helping support efficient cooling cycles.
-
Easier, Cleaner Installations
• Pre‑assembled sets cut down on fabrication time, reduce field brazing, and help ensure straight‑through refrigerant paths for peak system operation.
Q&A
Q: What is this line set used for?
A: This copper line set connects an outdoor air conditioner or heat pump to the indoor evaporator coil, allowing refrigerant flow between units in central HVAC systems.
Q: What sizes are the liquid and suction lines?
A: Liquid line diameter is 3/8″ and suction line diameter is 1 1/8″, making it suitable for 3 ton to 5 ton systems.
Q: How long is the line set?
A: The total length of this line set is 50 feet, which covers typical installation distances for residential and light commercial applications.
Q: What material is it made from and why?
A: It’s made from high‑quality copper tubing, which is corrosion‑resistant, durable, and easy to form for bends during installation.
Q: Can this line set be insulated?
A: Refrigeration line sets typically require insulation on the suction line to prevent condensation and improve efficiency — check specific product details or add insulation as needed.
Q: Why choose a copper line set over alternatives?
A: Copper offers excellent conductivity, long service life, and ease of brazing/joining, which helps ensure a reliable, leak‑free connection in HVAC systems
Maintenance Tips
-
Inspect for Leaks or Damage
Regularly check joints, bends, and connections for signs of corrosion, kinks, or refrigerant leaks.
-
Keep Line Set Clear and Supported
Ensure proper mounting and support to avoid sagging or stress on fittings.
-
Insulate Refrigerant Lines
Maintain high-quality insulation on the suction line to prevent energy loss and condensation buildup.
-
Protect from Outdoor Elements
Shield the line set from direct sunlight, sharp objects, or extreme weather to prevent deterioration.
-
Check Connections During System Maintenance
Whenever the AC or heat pump is serviced, have a technician inspect line set connections for tightness and integrity.
