ICS Industries – 1″ TYPE K Hard Copper 5 Ft Length
Seamless Type K water tube designed for drinking water and plumbing applications. This hard copper tube meets ASTM B88 and is made from alloy 12200 copper, with Underwriters Laboratories and regulatory classifications. It is intended for systems with pH 6.5 and above, with NSF consideration for potential leaching in low-pH conditions. The product ships in a straight length with a +/- 5% cutting tolerance, suitable for rigid, high-pressure lines in residential or commercial settings.
Key considerations include compatibility with potable water standards and the need for corrosion control when exposed to acidic water. While it provides robust strength, ensure proper fittings and practices to maintain system integrity over time. The 1″ size is well-suited for main supply runs, service lines, or as a branch in larger copper networks.
YuJingKey Copper Tubing 1″ OD x 1 Ft
This 1″ OD copper tube comes in a compact 1-foot length and is made from C12200 copper, meeting ASTM B280 standards. It is designed for HVAC refrigerant lines and other tubing applications requiring seamless copper with strong thermal conductivity. The package includes two pieces and is suitable for short runs, service connections, or prototype setups where 1″ diameter is needed without long coil lengths.
Considerations include ensuring compatibility with refrigerants and pressure ratings, as well as the ease of cutting and flaring. Its high purity and seamless design support reliable performance in refrigeration and air conditioning systems. When used in potable contexts, verify pH compatibility per local code requirements and any applicable corrosion controls.
Eoiips Copper Round Tube 1”OD x 29/32”ID
Provided as a straight 10″ length tube, this 1″ OD copper tube features a 29/32″ ID and is described as a high-quality, seamless product suitable for precise copper plumbing and HVAC installations. It is described as easy to process and cut as required, making it practical for demonstrations, experimental setups, or small-bore distribution lines.
Safety and performance considerations include ensuring proper support for short segments and confirming that the tube’s pressure and temperature ratings meet your system’s demands. The seamless surface supports consistent flow characteristics and reduces potential leakage points in tight installations.
GOORY Copper Tubing 1/4″ OD x 0.195″ ID Coil
While this option is smaller than 1 inch, it demonstrates the breadth of copper coil tubing used in refrigeration and DIY projects. With a 1/4″ outer diameter and 0.195″ inner diameter, it provides excellent thermal properties for compact systems and can serve as a flexible link in multi-size copper networks. Material is specified as C12200, conforming to ASTM B280 standards, offering durability and resistance to oxidation in challenging environments.
GOORY Copper Tubing 3/4″ OD x 0.687″ ID Coil
This 3/4″ diameter tubing is also a solid pick for HVAC installations needing flexible coil tubing. It adheres to ASTM B280 for seamless construction and uses nitrogen-charged treatment to improve oxidation resistance and longevity. While smaller than 1″, it remains a strong alternative for branch lines, condensate paths, and compact refrigerant runs within larger copper networks.
Buying Guide: Key Considerations For 1 Inch Copper Coil Tubing
- Material and Standard Compliance: Look for copper tubes made from C12200 or similar alloys that meet ASTM B88 (for straight copper water tube) or ASTM B280 (refrigeration tubing). NSF/UL classifications can indicate suitability for drinking water, but confirm pH compatibility and any corrosion controls if your water is acidic.
- Type And Wall Thickness: Type K is generally thicker-walled and more robust for plumbing and high-pressure services. Evaluate whether your system’s pressure, temperature, and code requirements justify Type K versus other types.
- Diameter Precision: Ensure the exact outer diameter (OD) matches your fittings and manifolds. Although OD is critical, the internal ID also affects flow and pressure loss in longer runs.
- Length And Form Factor: Straight lengths are common for rigid runs, while coils offer flexibility for routing in tight spaces. Short 1 ft or 10 ft segments can be useful for service connections or prototype builds, but longer lengths reduce the number of joints.
- Installation Considerations: Flaring and brazing procedures must align with the system design. Cleanliness, deburring, and appropriate flux selection affect joint integrity and longevity.
- Environmental And Regulatory Context: In potable water lines, check local codes and consider corrosion-control strategies if water pH is low. For refrigeration and HVAC, verify compatibility with refrigerant types and operating temperatures.
- Cost and Availability: Availability varies by retailer; if you need recurring stock for service fleets, consider supplier reliability and lead times for 1″ copper coil tubing in both straight and coil formats.
