For connection from one coupling nominal size to another one, adapters are used. In the most important sizes the seal support is a swivelling centre section, so that the seals do not rotate on each other even when they are connected with adapters. When adapters are connected to hose couplings, the ribs of the clamp fittings are opposite each other in fully coupled condition.
