CLI Readi-Protector 5/8″ OD 100′ Gas Tubing
This flexible yellow polyethylene-coated copper tubing is designed specifically for LPG installations. It features continuous line markings for easy identification, indicating tube contents, ASTM specification, size, and lot number. The coating adds corrosion protection and supports both above- and below-ground use, making it suitable for outdoor gas lines and indoor connections alike. The tubing’s 5/8″ outer diameter and 100-foot length provide a practical balance of durability and reach for residential projects.
GOORY Copper Tubing 5/8″ x 50 ft
GOORY offers a 5/8″ OD, 0.57″ ID copper tube in a 50-foot seamless coil. Made from annealed UNS C12200 copper and conforming to ASTM B280, it delivers strong thermal conductivity and durability. While primarily positioned for refrigeration and HVAC, the copper tube’s flexibility and corrosion resistance make it a solid choice for gas-related installations where a reliable, traceable copper line is required. A nitrogen-charged treatment helps reduce oxidation and impurities, supporting tube longevity.
CLI Readi-Protector 5/8″ OD 50′ Gas Tubing
This 50-foot version mirrors the 100-foot option’s features: a yellow polyethylene jacket, continuous line markings for gas contents, and enhanced corrosion protection. The protective coating enables versatile use in both above- and below-ground gas installations. Its traceable markings simplify maintenance checks and compliance verification for LP gas systems.
5/8ODx100FOOT Yellow Coated Copper Tubing For Gas Service
Cupro’s 100-foot yellow-coated copper tubing is designed for gas service with a flexible, continuous line-marked coating. The tubing supports natural gas and LP gas installations, offering corrosion protection and ground compatibility. The markings aid in identification and traceability, ensuring compliance with safety standards during installation and future inspections.
5/8ODx50FOOT Yellow Coated Copper Tubing For Gas Service
Shorter runs still utilize the same protective yellow coating with continuous line markings for gas contents and specs. This option is ideal for projects with limited space or a need for a compact gas line that maintains traceability and corrosion protection across both above- and below-ground installations.
Buying Guide: 5/8 Copper Gas Lines
When evaluating 5/8 copper gas lines, these considerations help align product choice with project needs and safety requirements.
- Coating and protection: Yellow polyethylene jackets are common for gas lines, offering corrosion resistance and outdoor durability. Ensure the coating provides clear, continuous markings for contents, specification, and lot numbers.
- Length and flexibility: Choose length based on run distance, with longer coils simplifying installation but potentially increasing handling challenges. Consider whether a 50 ft or 100 ft length best fits your project plan.
- Traceability: Continuous line markings help identify contents and batch data, which is valuable for maintenance, code compliance, and safety audits.
- Material grade: Look for UNS C12200 copper or equivalent, with ASTM-B280 compatibility for refrigeration-type tubes repurposed for gas installations. Higher purity can improve durability and heat tolerance.
- Application suitability: Although many of these tubes are marketed for LPG and gas service, verify local codes and installer guidelines to ensure compatibility with your specific gas system (LP, natural gas, or propane) and installation environment.
- Above vs. below ground: Some coatings are designed for underground use, but always follow local code requirements for burial depth, protection, and tracing methods.
- Connections and fittings: Ensure the tube diameter and tolerances align with your fittings, regulators, and manifolds. Clean ends and proper support prevent leaks and vibration issues.
- Quality indicators: Look for nitrogen-charged treatments or oxidation-prevention processes as signs of longer service life and reduced maintenance needs.
- Code compliance: Confirm products meet ASTM standards and local gas installation codes. Proper labeling and traceability support inspections and safety compliance.
Safety and installation notes
Always follow manufacturer guidelines and local codes when cutting, bending, or joining gas copper lines. Use appropriate protective equipment, avoid kinks or crushing the tubing, and securely support long runs to prevent sagging. If in doubt, consult a licensed gas technician to ensure a compliant and safe installation.
