Filling the empty pipe with PU foam may give rise to small leaks. The GRAF
empty pipe seal made from PE foam is recommended.
Push the empty pipe seal into the empty pipe to
seal this tightly.
The hose surfaces and pipe walls must be cleaned
roughly and wetted slightly with water.
When filling the hoses with foam, make sure that
each of them is covered on all sides. For better
filling and enveloping, the hoses must be moved
slightly in the longitudinal direction.
