Description
The HVAC365 1/4" x 3/8" 35 Foot Copper Line Set is a refrigerant-piping assembly intended for ductless mini-split installations. It provides the paired copper tubing used to connect a compatible indoor unit and outdoor unit so refrigerant can circulate through the system. With a 35-foot length, this line set is suited to installations where the equipment locations require more distance than a short, direct connection. The listing identifies it as both pre-flared and insulated, helping reduce some of the tubing preparation normally completed in the field. It is a practical option for homeowners, HVAC contractors, and commercial buyers who have already confirmed that their equipment requires these exact tube sizes.
Key Features

- Paired 1/4-inch liquid line and 3/8-inch suction line copper tubing
- Pre-flared ends as identified in the HVAC365 product listing
- Insulated construction to help protect the refrigerant piping
- HVAC365 SKU 1438-35-HVAC365 for precise product identification
Compatibility / Installation Notes
Line-set selection must be based on the installation instructions for the specific indoor and outdoor units. Before ordering, confirm that the matched equipment calls for 1/4-inch and 3/8-inch refrigerant connections and allows a 35-foot piping run. A system’s capacity or general “mini-split” classification does not by itself confirm line-size compatibility.
The product page does not identify compatible brands or model numbers, refrigerant types, maximum allowable piping length, elevation limits, or whether additional refrigerant is required at this distance. Those details should come from the equipment manufacturer’s technical documentation. Buyers should also confirm what accessories are included; the listing does not state that communication wire, drain tubing, wall sleeves, line-hide covers, adapters, or mounting hardware are part of this line set.
Although the tubing is listed as pre-flared, the connections still need to be inspected and installed according to the equipment manufacturer’s requirements. Routing should avoid kinks, damage to the insulation, and bend conditions that could restrict the tubing. Final connection, leak testing, evacuation, refrigerant-charge verification, and system commissioning should be handled by a qualified HVAC professional. HVAC365 states that warranty validation requires installation by a qualified licensed professional in accordance with local codes and the manufacturer’s installation requirements.
Frequently Asked Questions
What tubing sizes are included?
The line set contains 1/4-inch and 3/8-inch copper tubing. Confirm both required connection sizes in the mini-split installation manual.
How long is this line set?
It is 35 feet long. Verify that the planned route and the equipment manufacturer’s allowable line length are compatible before purchase.
Is the line set pre-flared and insulated?
Yes. HVAC365 identifies this product as pre-flared and insulated.
Will it work with any ductless mini-split?
No universal compatibility is stated. It should only be selected for a system that specifies 1/4-inch and 3/8-inch refrigerant piping and supports the planned 35-foot run.
Does it include wiring or a condensate drain hose?
The product page does not confirm those items. Review the package contents or contact HVAC365 before ordering if additional installation accessories are needed.
Review the equipment specifications and planned routing, then choose this HVAC365 line set when the 1/4-inch by 3/8-inch sizing and 35-foot length match the installation.
