Straight Copper Pipe 1/4″ to 2-1/8″ | Wisdo Merchants

Straight Copper Pipe for AC and Refrigeration Systems

Straight copper pipe gives installers neat, rigid pipe runs for air conditioning and refrigeration work. Each length is 5.8 metres. It comes in eight sizes, from 1/4″ for small split units up to 2-1/8″ for large commercial systems. Copper tubing is the standard choice for refrigerant lines because it moves heat well, holds pressure and resists corrosion. At Wisdo Merchants in Nairobi, we supply straight copper pipe to AC technicians, refrigeration contractors and maintenance teams across Kenya.

Why Choose Straight Copper Pipe

Straight lengths keep long runs tidy. They lie flat along walls, ceilings and pipe racks, so the finished installation looks clean and is easy to support. They are also the practical choice for larger diameters, which are hard to bend and coil.

For example, a supermarket cold room or a central chiller often needs long, large-bore suction lines. Straight pipe makes these runs simple to measure, cut and join. For smaller and shorter runs, our flexible coiled option may suit you better.

Straight Copper Pipe Features and Benefits

• Eight sizes in stock: 1/4″, 3/8″, 5/8″, 3/4″, 7/8″, 1-3/8″, 1-5/8″ and 2-1/8″.
• 5.8 m lengths: Long enough for most runs, so you need fewer joints.
• Neat, rigid runs: The pipe stays straight, which makes clipping and supporting it easy.
• Large-bore sizes: The 1-3/8″ to 2-1/8″ sizes serve big commercial and industrial systems.
• Good heat transfer: Copper moves heat well, which helps cooling systems run efficiently.
• Flare and braze ready: The pipe joins with standard flare fittings or brazing.

Technical Overview

Sizes are outside diameters in inches. Always follow the equipment maker’s guide when choosing liquid and suction line sizes.

Straight Copper Pipe Applications and Installation Tips

Our pipe suits:

• Split, multi-split and ducted air conditioning systems
• Cold rooms, chillers and freezer rooms
• Supermarket display cases and commercial kitchens
• Hotels, hospitals and factory cooling plants
• Repairs and line extensions on existing systems

Smaller sizes usually serve liquid lines and domestic units. Larger sizes, from 7/8″ upward, usually serve suction lines and bigger commercial plants.

Installation tips:

1. First, measure the run and mark each cut point.
2. Next, cut the pipe square with a refrigeration tube cutter and remove any burrs.
3. Then join the pipe with a flaring tool kit, or braze it using a MAPP gas cylinder and torch.
4. After that, clip the pipe securely and cover it with pipe insulation to stop condensation.
5. Finally, evacuate the system with a vacuum pump and test every joint with a refrigerant leak detector.

Safety and Handling

Keep the pipe ends capped until use, because dirt and moisture inside can damage the system. Store the lengths flat and supported so they do not bend or dent. Cut ends can be sharp, so wear gloves.

When brazing, work in a well-ventilated area and keep flammable materials away. Wear eye protection and heat-resistant gloves. Only trained technicians should handle refrigerant and pressurised systems.

Frequently Asked Questions

Which sizes do you stock?
We stock 1/4″, 3/8″, 5/8″, 3/4″, 7/8″, 1-3/8″, 1-5/8″ and 2-1/8″.

How long is each pipe?
Each straight length is 5.8 metres.

Should I use straight or coiled copper?
Straight lengths suit long, neat runs and large diameters. Coils suit short, bendy runs on smaller systems.

Which size do I need?
It depends on the system capacity and the maker’s guide. Send us the model or capacity, and we will help you choose.
