Upgrade your natural gas or propane setup with this **100-foot 3/4″ CSST (Corrugated Stainless Steel Tubing) gas line kit**—designed for high-performance, safety, and versatility. Built with a **0.63″ inner diameter and 0.79″ outer diameter**, this flexible tubing delivers **up to 150,000 BTU/hour** of flow capacity, making it ideal for larger appliances like grills, fire pits, or water heaters. The **one-piece stainless steel SUS304 core** ensures corrosion resistance, while the **UV-resistant yellow polyethylene jacket** protects against outdoor elements.

The seamless, corrugated design eliminates weak connection points, reducing the risk of leaks and simplifying installation. It bends easily around obstacles, making it perfect for tight spaces like attics, basements, or outdoor setups. **For underground use, it must be installed within a non-metallic, water-tight conduit at least ½" larger than the tubing’s outer diameter**—never buried directly. The kit includes **two male adapter fittings** for quick setup, and Grehitk offers **90-day hassle-free returns or replacements** if needed. Always follow proper installation guidelines to ensure safety and performance.
