The KUMA-1 and KUMA-n type flanged end seals are designed for sealing installation passages through building partitions (single or multi-pipe passages). They are used in non-pressure conditions (up to 2 meters of water column height) and protect against migration of water, mud and gas along the pipeline.

The tightness between the seal and the pipe(s) is ensured by clamping a stainless steel or steel-plastic band.

The tightness between the seal flange and partition is obtained by tightening the seal with a steel or plastic flange using screws (expansion pins). The flanges can be one-piece or segmented.
