2 Inch Type M Copper Pipe — 6.0 Inch Length
Premium Type M copper tube, ASTM B88 certified, designed for medium pressure water, hydronic heating, and gas distribution systems. This tube is suitable for potable water lines, refrigeration, chilled water, and vacuum systems. It withstands continuous service in hot and cold applications up to 400 degrees F, depending on size and pressure. It is compatible with standard copper fittings, including solder/sweat fittings, press-fit (Viega ProPress, Nibco Press), and compression or flare fittings, and it can be joined with lead-free solder or brazing alloys. Manufactured in the USA or Mexico to ASTM B88 standards, this tube is a versatile choice for residential, commercial, and HVAC projects.
2 Inch Type M Copper Pipe — 18.0 Inch Length
This 2 Inch Type M copper pipe shares the same ASTM B88 certification and versatility as the shorter variant, but comes in a longer 18.0 inch length for easier installation in continuous runs. Ideal for potable water lines, refrigeration, and HVAC systems, it offers robust performance under sustained service in both hot and cold conditions. It remains compatible with standard copper fittings, including solder/sweat connections, press-fit options, and compression or flare fittings, ensuring straightforward integration with existing copper systems.
ICS Industries 2″ Type M Hard Copper (5 Ft Length)
Seamless hard copper tubing in Type M, ASTM B-88 standard. This 5 ft length is evaluated for drinking water applications per ANSI/NSF classifications. The alloy (12200) supports robust durability under typical plumbing pressures. The tubing is cut to length with a tolerance of ±5%, offering a practical option for longer installations and custom runs. It is compatible with standard fittings and designed for reliable performance in residential and light commercial projects.
EZ-FLUID 2″ C X MIP LF Copper Male NPT Adapter
Lead-free copper male adapter with C X MIP threads, enabling a secure transition from copper tubing to NPT threaded connections. This adapter is designed for stress-free sweat connections on Type M, L, or K copper tubing, and supports residential or commercial installations requiring threaded pipe segments. It complements standard fittings and is offered in lead-free copper for safer potable water systems.
EZ-FLUID 2″ Solder LF End Cap
Lead-free copper end cap for 2″ copper piping, providing a snug, sweat-solder connection to terminate runs. This end cap is suitable for Type M, L, or K copper tubing and supports both residential and commercial applications where pipe termination is required. It is designed for reliable seal integrity and corrosion resistance in hot and cold service environments.
Buying Guide
- Type M vs Type L: Type M is standard-wall copper suitable for lighter to medium pressure systems, while Type L has a heavier wall for higher pressure and more demanding applications. For long runs in high-temperature HVAC or pressurized water lines, Type L may offer added safety margin.
- Tube size and specifications: Confirm the exact OD and ID (e.g., 2.125″ OD, about 2.009″ ID). Ensure compatibility with fittings and connectors you plan to use, whether soldered, pressed, or threaded.
- Fittings compatibility: Check whether your project requires solder-sweat, press-fit (Viega ProPress, Nibco), or compression/flare fittings. Some products are designed to be interchangeable with multiple fitting types.
- Working temperature and pressure: Look for tubes rated for continuous service up to 400 degrees F, and review the pressure rating for your specific wall thickness and diameter. This ensures reliability in hot water heaters, boilers, and cooling systems.
- Certification and quality: ASTM B88 certification ensures standard quality for potable water and HVAC uses. UL/NSF classifications or similar verifications indicate suitability for drinking water applications and safety compliance.
- Manufacturing origin: Tubes manufactured in the USA or Mexico to ASTM B88 standards may have stricter quality control and traceability, which could matter for compliance and long-term service life.
- Specialty adapters and fittings: When planning to connect copper tubing to NPT threads or other non-copper systems, select compatible LF (lead-free) adapters or end caps to maintain safety and code compliance for potable water.
- Availability and stock: Longer lengths (like 18.0″ tubes) reduce the number of joints, potentially decreasing leak risk but may require cutting on-site to fit. Shorter lengths offer modularity for custom layouts.
- Application scope: For beer brewing, refrigeration equipment, or sanitary systems, consider specialized ferrules, clamps, or tri-clamp adapters to maintain sanitary standards and leak-tight performance.
- Installation considerations: Ensure you have the right tools for soldering (lead-free solder appropriate for the chosen alloy) or for pressed fittings, if your system uses press-connect hardware.
