100 ft Insulated Copper Line Set for HVAC Systems
Looking for a reliable 100 ft mini split line set for extended HVAC installations? This 1/4" x 3/8" insulated copper line set is designed for efficient refrigerant transfer, high pressure resistance, and long-distance performance.
Perfect for mini split air conditioners, heat pumps, and residential HVAC systems, this line set ensures stable operation even in complex layouts.
This mini split line set includes two copper tubes (liquid line + suction line) pre-insulated for improved efficiency and faster installation.
Manufactured from 99.9% pure copper (C12200) and compliant with ASTM B280, it delivers excellent thermal conductivity and corrosion resistance—critical for long-term HVAC reliability.
Key Features of 1/4" x 3/8" x 100 ft Mini Split Line Set for HVAC Systems
High-Purity 99.9% Copper for Maximum Efficiency
Premium copper ensures:
Superior heat transfer Reduced energy loss Long service life
Think of it as a high-speed pipeline for refrigerant flow.
Professional drivers
Built to meet international HVAC standards:
ASTM B280 refrigeration copper tubing C12200 DHP copper grade
Ensuring safe and durable operation in HVAC systems.
High Pressure Rating (2100–7000 PSI)
Supports modern refrigerants such as:
R410A R32
With pressure capacity far exceeding standard requirements—ensuring leak-free performance.
100 ft Long Line Design for Flexible Installation
This extended length is ideal for:
Long-distance indoor-to-outdoor connections Multi-room setups Complex building layouts
Perfect when installation flexibility is essential.
Standard Size for Small HVAC Systems
Liquid Line: 1/4" (6.35 mm)
Suction Line: 3/8" (9.52 mm)
Commonly used for: 9,000 – 12,000 BTU mini split systems
Features of pipe insulation tubing
Pipe Insulation, Material Black Rubber, Temp Range -40 Degrees to 120 Degrees.
The pipe insulation has a better function of moisture condensation. Insulation material is both the insulation layer and moisture-proof layer.
There is no need to drop the water vapor permeation protective layer so that it has a better moisture condensation function.
Detail of 1/4" x 3/8" x 100 ft Mini Split Line Set for HVAC Systems
Advanced Insulation Technology for Maximum Performance
UV-Resistant & Flame-Retardant Insulation
