WADEX Chimney Inner Sleeve 126 Reverse D180/160 mm

The WADEX Chimney Inner Sleeve 126 Reverse D180/160 mm is a professional-grade transition component engineered to facilitate secure and airtight connections within flue gas ventilation systems. This specialized reverse sleeve is designed to bridge the gap between different pipe diameters, specifically transitioning from a 180 mm opening to a 160 mm connection. Crafted from high-quality, heat-resistant materials, this component ensures the structural integrity of your chimney system while promoting efficient exhaust flow for residential heating installations.

Advantages

The primary benefit of this WADEX chimney sleeve is its precise engineering, which guarantees a snug and reliable fit between chimney sections of varying sizes. Its robust construction offers excellent resistance to the high temperatures and corrosive environments typically found in flue gas systems, ensuring long-term durability and safety. By providing a seamless transition, it helps maintain optimal draft conditions, which is essential for the efficient operation of heating appliances and the prevention of smoke leakage.

Suitable for

• Connecting chimney pipes with different diameters
• Residential flue gas ventilation systems
• Adapting existing chimney setups to new heating appliances
• Ensuring airtight transitions in exhaust ducting

When it may not be suitable

This component is not intended for use in systems where the diameter requirements fall outside the specified 180 mm to 160 mm range. It is also not suitable for industrial-grade exhaust systems that require specialized materials beyond standard chimney-grade steel or for applications involving non-standard flue gas temperatures.

Key specifications

• Diameter configuration: 180 mm to 160 mm
• Type: Reverse transition sleeve
• Material: Heat-resistant chimney-grade steel
• Application: Flue gas ventilation

How to use

To install the WADEX reverse sleeve, ensure that the chimney system is completely cooled and the flue is clear of debris. Insert the sleeve into the larger pipe section first, ensuring a firm fit, and then connect the smaller pipe section into the opposite end of the sleeve. Use appropriate heat-resistant sealant or mechanical fasteners if required by local building codes to ensure the connection remains airtight and stable during thermal expansion.

What to consider before purchase

• Verify the exact outer and inner diameters of your existing chimney pipes
• Check local building regulations regarding chimney component compatibility
• Ensure the material is compatible with your specific heating appliance type

Usage recommendations

Regularly inspect the connection point during annual chimney maintenance to ensure that no soot buildup or thermal degradation has compromised the seal.
