KAERMO 3/4" CSST Flexible Gas Line 100FT — Corrugated Stainless Steel Tubing with Brass Fittings

KAERMO 100FT 3/4" CSST is a corrugated stainless steel flexible gas line kit designed to deliver propane or natural gas to grills and appliances with durable 304 stainless inner bellows and solid brass end fittings.

This 100-foot, 3/4-inch corrugated stainless steel tubing provides a long, flexible run for indoor or outdoor gas installations where a reliable, corrosion-resistant supply line is needed. The tubing combines a 304 stainless steel inner corrugation for flow and flexibility with a thick PVC outer jacket for abrasion and heat protection. Two male brass adapter fittings are included so you can connect common grill and appliance fittings without resorting to temporary rubber hose solutions.

How does this CSST compare to rubber or PVC grill hoses?

Unlike rubber or thin plastic hoses, this CSST uses 304 stainless steel bellows that resist corrosion and maintain shape under bends. The thicker outer jacket reduces surface damage and the brass fittings offer secure, long-term connections that stand up to repeated installations.

• 304 stainless corrugated inner tube resists rust and fatigue
• Thickened PVC outer jacket protects from abrasion and heat
• Solid brass end fittings for durable, leak-resistant connections
• Meets needs for longer runs where rubber hoses would sag or deteriorate

Can I cut and route this line for my specific layout?

Yes. The tubing is designed to be cut to length and routed through attics, basements, walls or along exterior runs. Its corrugated construction lets you bend around corners while maintaining internal flow, but follow local codes when passing through structures or burying it underground.

• Cut-to-length flexibility for custom installations
• Bends easily for tight spaces without restricting gas flow
• Not recommended to be buried without non-metallic watertight conduit at least 3/4" larger than pipe OD
• Suitable for exposed, concealed or embedded installations where code allows

What appliances and uses are suitable for this 3/4" gas line?

The 0.55" inner diameter supports higher flow appliances and longer runs, making it appropriate for large grills, pizza ovens, patio heaters, gas stoves, water heaters, dryers and other propane or natural gas equipment. Always verify appliance requirements and local codes before installing.

• BBQ grills and outdoor kitchen appliances
• Gas stoves, water heaters, dryers and patio heaters
• Pizza ovens and larger low-pressure gas equipment
• Indoor or outdoor connections where a longer, high-flow line is needed

What safety and installation notes should I follow?

The tubing is manufactured in a one-piece form to minimize mid-run joints, reducing potential leak points. Pressure-tested layers enhance reliability, but correct installation, protected routing, and compliance with local regulations are essential for safe operation.

• One-piece molding reduces connection points and leak risk
• Three-layer pressure testing on each tube for quality assurance
• Do not bury without appropriate non-metallic watertight conduit sized 3/4" larger than the pipe OD
• Use brass adapters and approved fittings; follow local codes and inspectors' guidance

Who is this for: Homeowners, contractors and grill enthusiasts who need a robust, long-run gas connection will appreciate the KAERMO 100FT 3/4" CSST line. It suits anyone installing larger appliances or outdoor kitchens that require higher flow and a durable, flexible tubing solution—provided installations are carried out to code and inspected where required.
