1-1/4" ID x 20' Copper Tubing, Straight Hard, Type L

Streamline LH12020 – 1-1/4" x 20' Type L Copper Tubing (Hard, Straight Length) The Streamline LH12020 is a 1-1/4 inch nominal size, 20-foot straight length of hard-drawn Type L copper tubing, designed for pressure systems in commercial and residential construction. Manufactured to meet applicable ASTM and NSF standards, this product delivers consistent wall thickness, uniform temper, and reliable mechanical strength for water distribution and other fluid-handling systems. Product Highlights Type L Hard-Drawn Copper – Mid-weight copper tubing suitable for indoor potable water supply, HVAC, and general plumbing Standardized Sizing and Color Code – Each length is incised marked and color-coded in accordance with industry norms for Type L (typically blue) Straight 20' Length – Reduces the need for couplings and minimizes pressure drop due to fewer joints Reliable Operating Limits – Rated for 373 psi at 100°F and service temperatures up to 200°F Lead-Free and Code Compliant – Conforms to ASTM B88 and is certified to NSF/ANSI 61 and NSF/ANSI 372 Technical Data Material: UNS C12200 seamless copper Type: Type L (hard temper, straight length) Nominal Size: 1-1/4" Outside Diameter: 1.375 inches Wall Thickness: 0.055 inches Length: 20 feet Pressure Rating: 373 psi at 100°F Max Temperature: 200°F continuous service Certifications: ASTM B88, NSF/ANSI 61, NSF/ANSI 372, lead-free compliant Common Applications Potable water supply lines Hydronic heating systems Commercial mechanical systems General fluid transfer within code-approved limits Installation Considerations Cutting, reaming, and soldering or brazing are required for assembly. Proper support spacing and expansion considerations must be followed per local code and system design. For press-fit or flare systems, ensure compatibility with fitting manufacturer guidelines. Use only approved joining methods for Type L copper.
