TP type bushings (transition sleeves) are designed for tight passages through building partitions. They are used in non-pressure conditions (up to 2 meters of water column height) as well as in pressure conditions up to 30m of water column (in the case of TP sleeves with mounted KU flanges) and protect against migration of water, mud and gas along the pipeline.

Permanently installed in the partition, they protect against the migration of water along the sleeve and are used to place a seal in them to ensure tightness between the sleeve and the pipe.
