Product Details

Description

The Centrotherm 2-inch Flex to Single Wall Adapter is a professional-grade venting component designed to create a secure, airtight transition between flexible polypropylene vent liners and rigid single-wall exhaust pipes. This adapter is essential for modern high-efficiency (condensing) appliance installations, including furnaces, water heaters, and boilers. Engineered to withstand the corrosive nature of flue gas condensate, it ensures a reliable seal and long-lasting performance in residential and commercial HVAC exhaust systems. It is highly versatile, providing compatibility with common piping materials such as Schedule 40 PVC, 636 PVC, S636, and ABS. Whether you are performing a new chimney liner installation or a system repair, this connector provides the necessary transition point for safe and efficient gas venting that meets modern building standards.
