Cerro Flow 1/2 in. D X 20 ft. L Copper Type L Tubing is a reliable, easy-to-handle solution for everyday plumbing and HVAC connections. This 20-foot coil delivers a dependable balance of strength and flexibility, designed to simplify installations in tight spaces without sacrificing durability. With a 0.04" wall and an actual outer diameter of 5/8", it’s built to withstand typical residential and light commercial use while remaining easy to bend and route.
-
Nominal diameter: 1/2" copper tubing (Type L) for standard residential and light commercial water runs.
-
Coiled convenience: A continuous 20 ft coil reduces the number of fittings and joints, speeding up runs behind walls, ceilings, and cabinetry.
-
Durable construction: High-quality copper resists corrosion and provides long-term reliability in both hot and cold potable water systems.
-
Precise sizing: 0.04" wall thickness with OD of 5/8" offers a solid balance between flow capacity and rigidity for easy routing.
-
Versatile compatibility: Compatible with common copper fittings, whether you sweat-solder or use compression connections for a secure seal.
Ideal use cases
- Residential cold and hot water supply lines, water heater connections, and appliance hookups (dishwashers, ice makers, water filtration).
- Remodels and new construction where a reliable, pre-coiled copper run minimizes fittings and potential leak points.
- HVAC and refrigerant line work in smaller-scale installations where flexibility and ease of routing are priorities.
- Concealed installations behind walls or in ceilings where a clean, long run reduces the need for joints and solder connections.
Why choose Type L and this Cerro Flow coil
Type L copper tubing hits a practical middle ground between wall thickness and flexibility, making it the go-to choice for most home plumbing and many HVAC applications. The Cerro Flow coil format enhances on-site efficiency by keeping the run continuous, minimizing the gaps where leaks can occur and reducing the number of crimp or solder joints you need to manage. Copper’s natural durability and corrosion resistance translate to fewer maintenance concerns and a longer service life for your water and heating systems.
Practical tips for installation and care
- Cut with a standard copper tubing cutter and deburr the end for a clean fit.
- Support the coil to prevent kinking; uncoil progressively as you route the line to maintain smooth bends.
- Use appropriate fittings—compression or sweat-solder—based on your project requirements and local code.
- Avoid exposing the tubing to extreme heat or direct flame; route away from heating ducts or radiant surfaces where feasible.
- Store flat or loosely coiled in a cool, dry place to preserve shape and prevent deformation.
Cerro Flow 1/2 in. D X 20 ft. L Copper Type L Tubing is a practical, proven choice for dependable water and utility connections. Its coil format, durable Type L construction, and compatible sizing make it a smart, code-friendly option for professionals and DIYers tackling modern plumbing and HVAC projects.
