5/5
(21 Ratings)
Metal sleeve used to connect two sections of pipe. You can extend the pipe further if needed, and it would be difficult to securely splice two pipes without one of these.
Description
Metal coupling sleeve for ventilation ducts
The metal coupling sleeve is an essential accessory for any ventilation, air conditioning, or extraction system. Its main function is to join two ducts of the same diameter securely, ensuring a firm connection without air leaks. This component is designed to offer a clean, quick, and efficient installation, ideal for both indoor growing and industrial or domestic ventilation systems.
Secure and Airtight Connection
Thanks to its precise design and manufacturing from high-quality galvanized metal, this sleeve ensures a perfect coupling between duct sections. With it, you can extend a 10-meter duct or connect two cut sections without the need for complicated tools or additional adapters. It is the perfect solution when you need to expand your installation or repair an existing section of the ventilation system.
Versatility and Total Compatibility
The metal coupling sleeve is available in different diameters to adapt to all standard duct sizes. You can use it for flexible or rigid ducts, both metal and plastic, always ensuring a stable connection. It is ideal for air extraction ducts, air conditioning systems, or grow room ventilation, offering total compatibility with other system accessories, such as clamps, reducers, or T-connectors.
Simple and Hassle-Free Installation
Installing the sleeve is very simple: just insert each end of the duct into the sleeve until it is well-fitted. For a firmer attachment, it is recommended to secure the joint with metal clamps or aluminum tape. Its robust design prevents leaks and reduces vibrations, ensuring quiet and stable operation even in high-power or high-pressure systems.
Durability and Resistance
Made from anti-corrosion galvanized metal, this sleeve resists humidity, heat, and wear, offering a long service life even in demanding environments. It is perfect for long-term installations where reliability and safety are required, preventing deformation or breakage over time. In addition, its smooth surface facilitates cleaning and maintenance of the ventilation system.

Actually quite good, but on one of four the seal was a bit porous. Had to fix it myself. A pity really for the price.
Translated from German
Eigentlich ganz gut, aber bei einem von vieren war die Dichtung etwas porös. Musste ich selbst nachbessern. Schade eigentlich für den Preis.

Used this for my new hydroponic system. Works well so far, but will it last long-term? No idea. Anyone have long-term experience with it?

It jammed a bit at first, was really tight. Went on with a bit of force. Now it sits tight though. You really should check the size carefully!
Translated from German
Hat anfangs etwas geklemmt, war echt eng. Mit etwas Kraft ging's dann. Jetzt sitzt es aber fest. Die Größe sollte man wirklich genau checken!
