Centrotherm 250406201370 Polypropylene Vent Elbow 87 Deg 4 in

Product Description

The CENTROTHERM 250406201370 is a 4-inch gasketed polypropylene vent elbow designed for high-efficiency condensing appliance exhaust systems. The 87-degree bend angle accommodates directional changes in plastic vent runs while maintaining a sealed, airtight connection through an integrated gasket. Rated to 230 degrees F, this elbow is suitable for the acidic condensate and elevated flue gas temperatures produced by condensing furnaces, boilers, and water heaters vented through Category IV vent systems. Licensed HVAC technicians and plumbers install this component as part of a complete polypropylene vent assembly.

This elbow is used in residential and light-commercial applications where a Category IV polypropylene vent system is required. Common install scenarios include condensing gas furnace flue runs, condensing boiler exhaust routing, and high-efficiency water heater venting where corrosion-resistant plastic vent pipe is specified. The gasketed socket connection allows secure joining without adhesives, simplifying assembly during rough-in and service.

Key Features

• 87-degree elbow geometry for near-right-angle directional changes in vent runs
• Gasketed socket connection provides an airtight, leak-resistant seal without adhesives
• Polypropylene construction resists acidic condensate and flue gas corrosion
• Rated to 230 degrees F for use with condensing appliance exhaust temperatures
• 4-inch diameter fits standard Category IV polypropylene vent pipe of the same size

Compatibility

Designed as an OEM-style component for 4-inch polypropylene Category IV vent systems used with condensing furnaces, boilers, and water heaters requiring corrosion-resistant plastic venting.

Installation Notes

Installation should be performed by a licensed HVAC technician or plumber in accordance with the appliance manufacturer instructions and local mechanical codes referencing the IFGC or IMC. Shut down and de-energize the appliance and allow the vent system to cool before disassembling any vent components. Verify gasket seating on all joints before returning the system to service. Support vent runs per code to prevent stress on elbow connections.
