Flue Pipe Clamp with Rubber Gasket Almeva ZUB DN80/125

The Almeva ZUB flue pipe clamp DN80/125 with integrated rubber gasket is a metal coupling designed to join and seal circular duct components with nominal diameters between DN80 and DN125. Manufactured for use in flue, chimney and HVAC exhaust assemblies, the clamp secures axial connections while the molded gasket provides a gas- and smoke-resistant seal to reduce leakage and prevent soot or condensate escape.

Advantages

The clamp combines a rigid metal body with a continuous elastomer gasket to deliver a reliable, compressive seal on round ducts. Its stepped DN80/125 profile allows compatibility across adjacent pipe sizes without additional adapters. The integrated rubber gasket simplifies installation by eliminating the need for separate sealing materials, and the clamp design permits consistent mechanical tightening for repeatable joints.

Suitable for

• Joining circular flue and chimney pipes in domestic and light-commercial exhaust systems
• Sealing HVAC exhaust runs and ventilation ducts where a gasketed connection is required
• Repair or replacement of existing connector joints between DN80 and DN125 components

Key specifications

• Nominal diameter range: DN80 to DN125
• Construction: metal clamp body with integrated rubber/elastomer gasket
• Application: circular duct connections for flue, chimney and HVAC exhaust systems
• Sealing: continuous molded gasket for gas- and smoke-resistant joint
• Mounting: mechanical tightening to secure axial pipe connection

How to use

Verify that the mating pipe ends are clean and free of debris, soot or corrosion before fitting. Position the clamp over the overlapping pipe ends so the gasket contacts both surfaces evenly. Tighten the clamp's fastening mechanism evenly until the gasket compresses and a firm, leak-resistant joint is achieved; avoid overtightening which could deform the gasket or clamp. Inspect the sealed connection visually and by smoke or pressure test if required by installation standards.

Usage recommendations

Use this clamp on compatible circular metal duct sections within the specified DN80–DN125 range and in systems designed for gasketed mechanical connections. Do not use on damaged or severely corroded pipe ends. Follow local building codes and appliance manufacturer instructions for flue and chimney installations, and perform periodic inspections to confirm continued sealing integrity.
