Material
Just like our spiral ducts, the couplers are produced to the highest standards. They are galvanised (Z275) according to the sendzimir process, making them durable in use and guaranteeing a long service life.
Air tightness class
The spiral duct female coupler meets the strict requirements for airtightness class D (ATC 2), according to standard EN12237.
Ease of installation due to rubber seal on fittings
The rubber seal, fitted to our fittings as standard, not only ensures an airtight connection, but this so-called safe-connection also ensures that further assembly materials are required to a limited extent.
