Flue Collar Poujoulat 80x125 mm model 7719001945 for chimney systems

Poujoulat flue collar 80×125 mm (model 7719001945) is a metal connector engineered for linking rectangular chimney or duct sections with an 80×125 mm profile. Designed by Poujoulat for ventilation and flue gas conduits, the collar provides a precise mechanical fit that helps ensure stable connections between chimney components and simplifies alignment during installation. The product is intended for use where a rectangular-to-rectangular joint or reinforcement of a duct section is required in heating and exhaust systems.

Advantages

The flue collar offers a rigid metal construction that maintains shape under typical operating conditions and supports reliable mechanical sealing between duct sections. Its dimensions match standard 80×125 mm profiles to reduce gaps and misalignment, making assembly faster and more accurate. The simple geometry allows for compatible attachment with common fasteners and sealants used in chimney installations, supporting long-term stability and serviceability of flue runs.

Suitable for

• Joining rectangular chimney sections with 80×125 mm profile
• Ventilation ducts where a durable mechanical connection is required
• Flue gas conduits in residential and light-commercial heating systems
• Repairing or reinforcing existing duct joints and transitions

Key specifications

• Material: metal construction suitable for duct and chimney applications
• Nominal profile size: 80 × 125 mm
• Shape: rectangular collar for matching rectangular duct sections
• Function: mechanical connector and sealing aid for ventilation and flue systems
• Compatibility: intended for standard rectangular chimney and duct profiles of corresponding dimensions

How to use

Position the flue collar so that its rectangular opening aligns with the mating 80×125 mm duct or chimney section. Slide the collar into place or fit it over the end of the duct, ensuring full contact along the joint. Secure the connection with appropriate fasteners or clamps and apply a suitable high-temperature sealant or gasket where required to achieve a tight flue seal. Verify alignment and clearance after fastening to maintain proper draft and safe exhaust flow.

Usage recommendations

Use compatible high-temperature sealants and corrosion-resistant fasteners for durable joints. Inspect connections after initial heating cycles and during routine maintenance to confirm seals and fastenings remain secure.
