Chimney Tee WADEX 109 Diameter – 130 mm 4"

Chimney Tee WADEX 109 Diameter – 130 mm 4" is a flue system fitting designed to provide a perpendicular branch and maintenance access in metal chimney installations. Intended for use where a 90° outlet is required, the tee allows connection of an inspection or cleaning port and can join an additional pipe run to an existing straight flue. The fitting is made to match a nominal 109 mm system with a 130 mm outside diameter, offering a compact and durable branching solution for residential and light commercial heating systems.

Advantages

The WADEX chimney tee offers straightforward integration into existing metal flue systems and enables convenient inspection and cleaning without dismantling long sections of pipe. Its construction provides a reliable 90° branch that maintains flue flow characteristics while allowing safe access for maintenance. The size compatibility with 109 mm nominal systems and a 130 mm actual diameter ensures a close fit to matching components and reduces the need for additional adapters.

Suitable for

• Creating a 90° branch in metal flue and chimney systems
• Adding an inspection or cleaning access point to a chimney run
• Connecting a secondary pipe run to an existing flue
• Residential solid fuel, gas or oil appliance flue installations that match the specified diameter

Key specifications

• Designed for nominal 109 mm flue systems with 130 mm outside diameter
• 90° perpendicular branch for inspection and cleaning
• Compatible with metal flue pipe components of matching diameter
• Compact design suitable for confined installation spaces

How to use

Install the chimney tee inline with the flue run where a perpendicular branch or maintenance access is required. Ensure both the main pipe and branch ends are clean and free of debris before joining. Slide or secure the mating pipes into the tee using the recommended connection method for the flue system (e.g., slip-fit, clamp or seal as applicable), keeping alignment tight to maintain draft and prevent leaks. Position the inspection or cleaning outlet at an accessible height to simplify routine maintenance.

Usage recommendations

Confirm that the flue system and appliance types are compatible with this tee size and material. Follow applicable local building codes and manufacturer instructions for sealing, support and clearances. Schedule regular inspections and cleaning to maintain safe operation and efficient draft performance.
