- High temperature resistance: The exhaust pipe of a gas water heater typically reaches about 140°C, while the thickened aluminum alloy pipe in this product is rated up to 500°C for added safety margin. - Thickened aluminum alloy construction: Thickened aluminum alloy body with a stainless steel outlet; sealed connections to resist cracking and leaks. - Extended length and connection: Flexible design extends up to 2 meters; can be stretched and bent to fit various installation routes. Includes a stainless steel butt joint for connecting multiple pipe sections. - Free shaping and easy installation: Easily stretched and formed to your required shape; simple to install and looks neat. - Applications and compatibility: Suitable for routing gas water heater exhaust in tight spaces, retrofit projects, or long vent runs with multiple turns; supports connecting several sections via the stainless steel joint. Use scenarios: - Retrofit or new installation where the vent path is long or winding and requires flexible shaping. - Replacement of worn exhaust piping with a high temperature resistant alternative. - Projects needing stops-and-starts in vent runs by linking multiple sections with the stainless steel joint.
