Streamline LH04020 – 1/2″ x 20′ Type L Hard Drawn Copper Tubing for Potable Water and Pressure ApplicationsThe Streamline LH04020 is a 20-foot section of 1/2″ nominal Type L copper tubing manufactured in hard temper. With a 5/8″ outside diameter and 0.040″ wall thickness, this tube is designed for above-ground pressure piping in residential and commercial plumbing systems. Type L copper is widely specified for interior potable water supply and HVAC system piping due to its balance of strength and workability.Manufactured in compliance with ASTM B88 standards, this tubing is suitable for use with soldered, brazed, or press-fit joining systems. It is color-coded and incised for traceable identification and job site accuracy.Product Specifications: Type: Type L (hard drawn)Nominal Size: 1/2 inchOutside Diameter: 5/8 inchWall Thickness: 0.040 inchesLength: 20 feetWorking Pressure: 613 psigMax Service Temperature: 200°FMaterial: Seamless copper, ASTM B88 compliantCertifications: NSF 61 listed for potable water applicationsMarking: Incised and color-coded (typically blue for Type L)Features: Pressure-Rated – Suitable for use in domestic water systems and mechanical applications requiring reliable pressure performanceCorrosion Resistant – Copper tubing offers long service life in both hot and cold water environmentsRigid Format – Straight lengths provide alignment accuracy and are easy to support and anchorCode-Compliant – Meets national and local plumbing code requirements for use in concealed and exposed installationsVersatile Use – Approved for potable water, HVAC refrigerant lines (where applicable), and hydronic systemsInstallation Considerations: Install using approved joining techniques such as soldering, brazing, or press systems compatible with Type L hard copper. Follow spacing guidelines for pipe supports and ensure compliance with local code regarding wall penetration, insulation, and protection from physical damage. Type L tubing is not rated for underground installation unless otherwise sleeved or protected.
