iSeal Duct Fittings

Our range of sealed duct fittings have built in EDPM rubber gaskets that not only minimise system leaks but also simplifies the installation process by removing the need for sealants or tapes. Aesthetically looks far superior and installation time is also massively reduced.

Benefits of sealed ducting

Ducting systems that utilise iDucts sealed fittings with built-in EPDM gaskets significantly reduce leakage, ensuring that conditioned air flows exactly where it’s needed. Industry-standard studies show that unsealed ductwork can result in energy losses of 20–30%, greatly diminishing the effectiveness of heating and cooling systems.  By minimizing air loss, sealed ducting enhances airflow balance and temperature control throughout the system, helping eliminate hot or cold spots and boosting overall ventilation efficiency.

The Benefits of Sealed Duct Fittings

Time-saving and leak-proof fittings

We understand that your team is busy, and time is of the essence. Our iSeal sealed duct fittings provide reduced installation time since there is no need to apply sealant solution; therefore, you can bypass the lengthy curing process. As soon as the ducting is installed, the ventilation system can be put into operation.

Sealed duct fittings are also easy to set up, require little maintenance and minimise air leaks. On top of that, they also boast superior aesthetics compared to regular fittings, as there will be no sign of any duct tape or messy sealant. As with the rest of the range, all our ducting parts are built to DW 144 – the industry standard.

How They Differ from Regular Fittings

Factory-installed sealing for a convenient solution

The double-lipped EDPM sealing gasket provides enhanced security against leakage. Furthermore, EDPM rubber is incredibly durable. An EPDM gasket can withstand temperatures from -30˚C to +100˚C. When installed as recommended, the built-in gaskets provide superior air tightness of class D. Our sealed duct fittings have rolled edges, making them safer to install and handle whilst providing extra strength. Another critical difference is that, while our standard duct fittings are typically more economical, sealed fittings are more convenient due to their superior durability and ease of installation.
