Slide-on stub for installation in ducts of type SR.
After the duct has been shortened/fitted, add sealant etc between the swaged seams on the slide-on stub, after which the slide-on stub is inserted into the duct. The two swaged seams guide and retain the slide-on stub.
To finish off, the edge of the stub is swaged, both to remove the sharp edge of the transition and to fix the slide-on stub.
Please refer to the shortening instruction on page InstructionTransfer.
Is also used as transition piece OTRTH between Transfer and flexible hose THVTR. See page THVTR.
