Product description

The UBA-BV made of stainless steel is a fire protection connector for floor-by-floor partitioning of cast iron pipes in domestic drainage systems and is installed in the cast iron pipe run. The fire protection connector closes the main pipe in case of fire. Alternatively, the fire protection connector can be mounted on the branch. This closes the branching line in case of fire. It has a continuous EPDM seal and protection against mechanical influences.
