KAERMO 100ft 1/2" CSST Flexible Gas Line for Propane & Natural Gas — Corrugated Stainless Steel, Brass Fittings

KAERMO 100FT 1/2" CSST is a corrugated stainless steel flexible gas line kit designed to carry propane or natural gas to grills, appliances, and heaters with durable brass fittings.

This 100-foot, 1/2" corrugated stainless steel tubing (CSST) from KAERMO provides a long, flexible run for gas installations where rigid pipe is impractical. The tubing combines a 304 stainless steel corrugated inner tube with a thickened PVC outer jacket and solid brass end fittings. It’s intended for low-pressure fuel lines serving BBQs, patio heaters, gas stoves, water heaters, dryers, and similar appliances — and it can be routed through tight spaces, attics, basements, or around obstacles.

How does this CSST make routing gas lines easier?

The corrugated stainless construction allows the line to bend smoothly around corners and through narrow runs without many fittings. That reduces the number of joints and simplifies installation in confined or unusual layouts.

• 100 ft length minimizes the need for extra couplings or long hard-piped runs
• Corrugated inner tube bends without kinking, preserving flow
• Cut-to-length convenience lets you trim exactly where needed
• Thin outer jacket protects against abrasion while remaining flexible

Is this product safe for indoor and outdoor gas applications?

The KAERMO CSST is built from corrosion-resistant 304 stainless steel with solid brass connectors; it undergoes multi-layer pressure testing to ensure integrity. It’s suitable for exposed indoor use and many concealed installations, though local code and protective conduit requirements must be followed for buried or exterior underground runs.

• 304 stainless steel resists rust in typical environments
• One-piece molded sections reduce intermediate joints and leak points
• Brass fittings provide durable, metal-to-metal connections
• Not to be buried without approved conduit at least 1/2" larger than the pipe

What appliances and systems can this tubing connect?

The half-inch inner diameter supports ample flow for many residential and light commercial gas appliances. It’s commonly used for grills, patio heaters, pizza ovens, gas ranges, water heaters, and dryers when a flexible, long-run solution is required.

• Barbecue and outdoor cooking appliances (propane or natural gas)
• Indoor gas stoves, ovens, and gas-fired water heaters
• Patio heaters and portable gas equipment requiring flexible runs
• Appliance conversion kits and retrofit installations

How do I install and maintain the KAERMO CSST safely?

Installation should follow manufacturer instructions and local building codes; use appropriate fittings and support clamps, and avoid burying the tubing without conduit. Periodic visual inspections for abrasion, damage to the outer jacket, and secure fittings will help maintain safe service.

• Trim with suitable tubing cutters, deburr ends, and fit brass adapters properly
• Secure with approved straps and keep away from sharp edges or heat sources
• Do not bury without a non-metallic watertight conduit larger than the pipe
• Have final pressure and leak testing performed per code after installation

Who is this for: Installers, contractors, and DIY homeowners who need a long, flexible half-inch gas run for grills, appliances, or heaters will find KAERMO's 100-foot CSST a practical choice. It’s especially useful where routing around obstacles, entering attics or basements, or minimizing joint count matters, but purchasers should confirm compatibility with local codes and, where required, hire a licensed gas fitter for final connection and inspection.
