7/8 Line Set 50ft – Refrigeration Copper Coil

7/8 Line Set 50ft Refrigeration Copper Coil

7/8 Line Set 50ft is an individual copper tubing coil designed for compatible HVAC and refrigeration installations. It has a nominal diameter of 7/8 inch and provides approximately 50 feet of continuous copper tubing.

The coiled format gives professional installers flexibility when measuring and routing refrigerant piping between compatible indoor and outdoor equipment. The tubing can be carefully cut according to the requirements of the installation.

7/8 Line Set 50ft Product Configuration

The 7/8 Line Set 50ft consists of one 7/8-inch refrigeration copper coil. Despite the current product name, it should not automatically be considered a complete two-pipe HVAC line set.

A typical split-system installation requires separate liquid and suction lines with different diameters. Another copper coil, insulation, fittings and additional installation accessories may therefore be required to complete the refrigerant circuit.

Review the exact equipment instructions before ordering. The outdoor and indoor unit documentation identifies the required liquid-line diameter, suction-line diameter, maximum equivalent length and permitted vertical separation.

Seven-Eighths-Inch Copper Tubing

The 7/8 Line Set 50ft has a nominal tubing diameter of 7/8 inch. This size is commonly used as a suction or vapor line in certain residential and light commercial HVAC systems, but compatibility varies by equipment.

Never select refrigerant piping based only on system tonnage or an existing connection. Manufacturers may specify different tubing diameters depending on refrigerant type, equipment combination, line length and elevation.

An incorrect diameter may affect refrigerant velocity, pressure drop, oil return, system capacity and compressor reliability. A qualified HVAC professional should verify the required tubing size.

Continuous 50-Foot Copper Coil

The 7/8 Line Set 50ft provides approximately 50 feet of continuous copper tubing. A continuous coil can help reduce the number of joints required between the indoor and outdoor HVAC components.

The tubing may be cut to the required length using an approved copper tubing cutter. Each cut should remain square, clean and free from burrs that could restrict refrigerant flow or introduce contaminants.

Store unused tubing with its ends properly sealed. Moisture, dust and construction debris must not be allowed to enter refrigeration piping.

Routing and Bend Protection

The 7/8 Line Set 50ft should be unrolled carefully rather than pulled sideways from the coil. Incorrect handling can flatten, twist or kink the copper tubing.

Use an approved tubing bender when necessary and maintain an appropriate bend radius. Do not install kinked, crushed or visibly damaged tubing because deformation can restrict refrigerant flow.

The completed route should be protected from sharp edges, impact, vibration and excessive movement. Appropriate supports should hold the copper securely without compressing or damaging it.

Refrigerant and Pressure Compatibility

Copper tubing compatibility must be verified for the refrigerant, pressure and equipment involved. Modern systems may use R-32, R-454B, R-410A or another refrigerant specified by the manufacturer.

Refrigerants must never be mixed or substituted. A2L refrigerants such as R-32 and R-454B require approved tools, components, installation procedures and safety practices.

Existing copper tubing should not automatically be reused for new equipment. A professional must evaluate its diameter, wall thickness, condition, cleanliness, previous refrigerant and manufacturer requirements.

Insulation Requirements

The 7/8 Line Set 50ft does not include insulation unless insulation is specifically identified with the product. A suction or vapor line typically requires correctly sized closed-cell insulation.

Proper insulation helps reduce heat gain and limits condensation on the exterior of a cold suction line. Required thickness depends on the equipment, refrigerant temperature, climate and installation location.

Exterior insulation may also require UV-resistant protection. Always follow the HVAC equipment manufacturer’s insulation specifications.

Professional Installation Required

Refrigerant-line installation should be performed by a qualified HVAC professional. The technician must verify pipe sizing, routing, supports, insulation, joining methods and equipment compatibility.

The copper must remain clean and dry throughout installation. When brazing is required, accepted HVAC procedures should be followed to reduce internal oxidation and protect nearby components from excessive heat.

The completed refrigerant circuit must be pressure tested, evacuated and commissioned according to the manufacturer’s instructions. Refrigerant handling must comply with applicable federal, state and local requirements.
