Kinchoix CSST Corrugated Stainless Steel Tubing — 37 ft 1/2" Flexible Natural Gas & Propane Line with UV Jacket and Brass Fittings

Kinchoix 37 ft 1/2" corrugated stainless steel tubing is a flexible, corrosion‑resistant gas line designed to carry natural gas or propane up to 100,000 BTU/hour for grills, ranges, heaters, and other appliances.

This 37‑foot CSST (corrugated stainless steel tubing) kit from Kinchoix combines a SUS304 inner tube with a yellow UV‑resistant polyethylene jacket and 1/2" male brass fittings on both ends. It is intended for connecting indoor or outdoor natural gas and liquid propane appliances where a long, flexible run is needed — from backyard grills and fire pits to water heaters, generators, and ranges. The corrugated design gives the line flexibility so it can snake through attics, basements, or around corners while reducing the number of joints required.

How strong is this gas line and what flow can I expect?

The tubing measures approximately 12 mm inner diameter by 16 mm outer diameter (0.48" ID x 0.63" OD) and is rated to deliver up to about 100,000 BTU/hour, suitable for many residential and light commercial appliances. The inner layer is stainless steel SUS304 for corrosion resistance, while the outer yellow jacket provides UV protection and easy visual identification.

• Internal diameter: ~12 mm (0.48"), outer diameter: ~16 mm (0.63").
• Flow capacity: up to ~100,000 BTU/hour depending on system pressure and fittings.
• Materials: SUS304 corrugated stainless steel core + yellow polyethylene jacket.
• Ends: 1/2" male brass fittings for standard threaded connections.

Where can I use this Kinchoix CSST — indoor, outdoor, or buried?

The tubing is suitable for a wide range of natural gas and propane applications: appliance connections, grills, fire pits, water heaters, generators and more. Its jacketed construction and high‑temperature resistance make it usable exposed indoors, behind walls in dry‑wall systems, and in many cases for burial or underground runs when local codes allow.

• Indoor appliance hookups: ranges, water heaters, furnaces (follow local codes).
• Outdoor uses: grills, fire pits, generators, yard appliances.
• Installation: can be routed through attics, basements, or embedded where permitted.
• Check local plumbing/gas codes for buried or concealed installations and required bonding/grounding.

How easy is installation and what safety details should I know?

The corrugated stainless construction bends easily to follow routes without many fittings, simplifying installs and reducing potential leak points. Each end features standard 1/2" male brass threads for quick connection; the tubing can be cut to length on site. As with any gas line, proper sealing, leak testing, and compliance with local codes and licensed installer requirements are essential.

• Flexible corrugated design minimizes extra fittings and bends neatly around corners.
• Comes with 1/2" male brass fittings for straightforward threaded connections.
• Cuttable to required length; always clean and deburr cut ends before connecting.
• Perform leak test after installation and follow local regulations and bonding requirements.
