1 in OD x 36 in Flexible Gas Connector for Tankless Water Heaters

In this review of the 1 in OD x 36 in Flexible Gas Connector, the bottom line is straightforward: this connector is aimed at homeowners and professional installers who need a high-capacity, durable gas line for tankless water heaters and other high-demand gas appliances. The most compelling reason to buy is its combination of heavy-duty corrugated stainless steel tubing and the patented SafeGuard yellow coating that resists corrosion, making it suitable for both indoor and outdoor installations. It arrives with brass fittings, PTFE sealant tape and a gas leak detector, so it is ready for a safe, professional installation.

Key Features

• 1 in Outer Diameter: Provides higher flow capacity for tankless water heaters and other high-demand gas appliances compared with smaller connectors.
• 36 in Length: Offers generous reach for typical installations without needing additional couplings or extensions.
• SafeGuard Coating: Yellow anti-corrosion coating protects corrugated stainless steel tubing from weather and common cleaning agents for outdoor or indoor use.
• Brass Fittings Included: Comes with both 3/4 in MIP (tapped 1/2 in FIP) and 3/4 in FIP brass fittings to fit common appliance connections.
• Complete Installation Kit: Ships with 4-mil PTFE sealant tape and a gas leak detector so installers can verify a sealed connection at installation.
• Certified and Tested: CSA certified and 100% leak tested for safe performance with natural gas and propane.

Who It's For

This connector is best for homeowners replacing or installing a tankless water heater who need a robust, high-flow gas line that is rated for indoor or outdoor use. It also suits professional plumbers and HVAC techs who want a ready-to-install assembly with fittings, sealant tape and a basic leak detector included.

Those who should look elsewhere include users who need a different length or diameter than 36 in or 1 in OD, or installers working with nonstandard fittings not compatible with 3/4 in MIP or 3/4 in FIP connections. For low-flow, small-appliance hookups a smaller connector will be more economical.
