Connection Sleeve for Round Flexible Ducts

A connection sleeve is a basic and essential element for properly laying out a ventilation route. If the standard length of a flexible duct coil isn't enough to reach from the distribution manifold to the desired room, this part allows you to securely and quickly splice two pieces of corrugated pipe. The sleeve ensures system continuity, eliminates pressure loss at the joint, and allows for the rational use of pipe remnants, minimizing waste on the construction site.

The part is molded from durable, rigid plastic and is designed for concealed installation in a floor screed or behind a suspended ceiling. Unlike the corrugated pipes themselves, the sleeve has a smooth inner surface. This design prevents air turbulence and does not create additional aerodynamic resistance, guaranteeing quiet and efficient operation of the heat recovery system throughout the building's entire service life.

Key Features and Benefits

• Versatility in system design. The sleeve is a completely independent element of the route. It is suitable for extending ducts regardless of which distribution boxes and manifolds are included in your project.
• Guaranteed joint tightness. The ends of the corrugated pipe are tightly inserted into the rigid sleeve. By adding rubber sealing rings to the pipe and subsequently securing the joint with aluminum tape, the connection is reliably protected against air leaks.
• Reliability for concealed installation. The part is manufactured according to the standards of ventilation corrugated pipes. This guarantees the absence of play during assembly and protects the joint from rupture even under the pressure of building mixtures during screed pouring.

Technical Specifications
