What Is Type M Copper Tube?
Type M is the lightest-wall classification among the commonly used Type K, Type L, and Type M copper water tube products. Because it uses less copper per foot, Type M can provide an economical option for installations where its wall thickness is approved by applicable plumbing codes and project specifications.
Hard-drawn Type M tubing is supplied as rigid straight tube rather than flexible coil, making it well suited for straight piping runs, building distribution systems, mechanical rooms, equipment connections, and other installations where rigid copper tubing is preferred.
Type M vs. Type L vs. Type K Copper Tube
Type M
- Lightest wall of the three common copper tube types
- Economical copper-tube option
- Commonly used in approved residential plumbing systems
- Best where Type M is specifically permitted by code and application requirements
Type L
- Medium-wall copper tube
- Heavier wall than Type M
- Common in residential and commercial plumbing
- Often selected when greater wall thickness is required
Type K
- Heaviest wall of the three common types
- Designed for demanding applications
- Commonly selected for water-service and underground installations
- Provides the greatest wall thickness for a given nominal size
Understanding Hard-Drawn Copper Tube
Hard-drawn copper tube is manufactured as rigid straight tubing. Unlike soft copper tube supplied in coils, hard copper maintains its straight shape and is intended to be cut, supported, fitted, and joined as part of a rigid piping system.
The 10-foot length provides easier transportation and handling than longer straight lengths and can be especially useful for service work, mechanical rooms, remodels, equipment connections, and installations with limited access.
Why Choose Type M Copper?
Economical Copper Piping
- Lower copper content than Type K and Type L
- Cost-effective for approved applications
- Excellent corrosion resistance
- Long service life when properly selected and installed
Easy Installation
- Rigid straight tube for clean piping runs
- Easy to cut and prepare using standard copper tools
- Compatible with widely available copper fittings
- Supports multiple approved joining methods
Common Applications
Plumbing & Water Distribution
- Residential potable-water piping where permitted
- Building water-distribution systems
- Fixture supply piping
- Mechanical-room piping
- Service and repair work
- Remodel and retrofit projects
Mechanical & Building Systems
- HVAC piping where approved
- Low-pressure mechanical piping
- Drainage applications where applicable
- Equipment connections
- General building-service piping
- Commercial and institutional installations where Type M is permitted
Joining Type M Copper Tube
Type M hard copper tube may be joined using several approved methods depending on tube size, service media, pressure, temperature, project specifications, fitting manufacturer requirements, and applicable codes.
- Soldered joints: commonly used for many potable-water and plumbing applications where permitted.
- Brazed joints: may be used where greater joint strength or specific system requirements call for brazing.
- Press connections: may be used with compatible copper press fittings and approved press systems.
- Mechanical connections: may be used with approved copper-compatible mechanical fittings.
Installation Guidance
- Confirm the required nominal copper tube size before ordering.
- Verify that Type M copper tube is permitted for the intended application.
- Confirm local plumbing-code requirements before installation.
- Inspect tubing for shipping or handling damage.
- Cut tubing square using an approved copper tubing cutter or saw.
- Remove internal and external burrs before assembling joints.
- Clean and prepare joining surfaces according to the selected joining method.
- Use compatible fittings designed for copper tube.
- Support horizontal and vertical tubing according to applicable code requirements.
- Use approved solder, brazing alloy, flux, press tools, and installation procedures as applicable.
- Pressure-test and inspect the completed piping system before placing it into service.
- Installation should be completed by qualified personnel familiar with copper piping systems.

Frequently Asked Questions
What is Type M copper tube?
Type M is a light-wall copper water tube classification commonly used in approved residential and building plumbing applications.
Is Type M thinner than Type L copper?
Yes. Type M has a thinner wall than Type L copper tube of the same nominal size.
Is Type M thinner than Type K copper?
Yes. Type K has the heaviest wall, Type L has a medium wall, and Type M has the lightest wall of the three commonly used copper water tube classifications.
What does hard copper tube mean?
Hard copper tube is rigid, straight tubing supplied in fixed lengths. It differs from soft copper tube, which is annealed and generally supplied in coils.
How long is each piece?
Each piece in this product family is supplied as one 10-foot straight length.
Is this copper tube sold by the foot?
No. This product is sold as a complete 10-foot stick. The displayed price applies to the selected 10-foot length.
Can Type M copper be used for potable water?
Type M copper is commonly used for potable-water distribution where permitted by local plumbing codes, project specifications, and system requirements.
Can Type M copper be used underground?
Type M is generally associated with approved above-ground building plumbing applications. Underground installations should use the copper-tube type specifically required by applicable codes and project specifications.
What is the difference between Type M and Type L copper?
Type M has a thinner wall than Type L. Type L is typically selected where additional wall thickness or broader application suitability is required.
What is the difference between Type M and Type K copper?
Type K has a much heavier wall than Type M and is commonly selected for more demanding applications, including many water-service and underground installations.
Can Type M copper tube be soldered?
Yes, when soldering is approved for the intended application and performed using compatible fittings, materials, preparation methods, and applicable codes.
Can Type M copper tube be brazed?
Yes, when brazing is appropriate for the application and completed using approved fittings, brazing alloys, procedures, and applicable codes.
Can press fittings be used with Type M copper?
Compatible copper press fittings may be used when the press fitting manufacturer approves the tube type, size, pressure, service media, and application.
Does Type M copper meet ASTM B88?
Type M copper water tube is manufactured to applicable ASTM B88 requirements. Confirm manufacturer documentation when project-specific certification is required.
Why choose a 10-foot length?
A 10-foot straight length is easier to transport and handle and can reduce unnecessary cutting and excess material on shorter piping runs, repairs, equipment connections, remodels, and confined installations.
