Chimney Union Tee WADEX 125 mm diameter — model 150/20

Chimney Union Tee WADEX 125 mm diameter — model 150/20 is a T-shaped flue fitting designed for 125 mm chimney systems. It provides a secure branch or junction point in exhaust pathways, allowing integration of additional pipe runs or access for inspection and cleaning. Constructed for use in solid fuel and gas chimney assemblies, this union tee supports routine installation and maintenance tasks where a 125 mm diameter connection is required.

Advantages

The WADEX chimney union tee offers a compact design that simplifies joining and branching of 125 mm flue pipes without altering the primary exhaust route. Its T-form allows straightforward access for cleaning or inspection, reducing the need for disassembly of long flue runs. The fitting is compatible with standard 125 mm chimney components, enabling consistent sealing and alignment when installed according to manufacturer recommendations.

Suitable for

• Creating a junction or branch in 125 mm chimney systems
• Providing inspection and cleaning access points in exhaust flues
• Installation and maintenance of solid fuel and gas chimneys with 125 mm diameter
• Retrofitting or extending existing 125 mm flue runs

Key specifications

• Nominal diameter: 125 mm
• Configuration: T-shaped union (tee) for branch connection
• Model reference: 150/20 (descriptive model identifier)
• Intended media: flue gases from solid fuel and gas appliances
• Function: connection, branching, inspection and cleaning access

How to use

Install the WADEX 125 mm union tee into the chimney run at the selected junction point, ensuring pipe ends are clean and free of debris. Align the tee with existing 125 mm flue pipes and engage the union connection according to the system's assembly method. Verify that seals or gaskets (if present in the system) are correctly positioned and that the joint is tight to prevent leakage of flue gases. Use the tee branch as an access point for inspection or to connect an auxiliary flue segment; secure all connections and complete any required sealing or clamping procedures before commissioning the appliance.

Usage recommendations

Use only in chimney systems rated for 125 mm diameter components and follow local regulations and manufacturer instructions for installation, clearances, and sealing. Ensure regular inspection and cleaning access via the tee to maintain safe exhaust flow; have installations checked by a qualified technician when used with gas appliances or where applicable codes require professional fitting.
