LIFECO Flexible Sprinkler Hose for Automatic Sprinkler Systems

The LIFECO Flexible Sprinkler Hose provides a reliable and efficient connection between the fire sprinkler branch line and the sprinkler head. Manufactured from corrosion-resistant AISI 304 stainless steel, the flexible hose allows the sprinkler position to be adjusted according to the final ceiling layout while supporting dependable performance in automatic fire sprinkler systems.

Each hose assembly is supplied with a lightweight galvanised bracketing system designed to provide secure sprinkler head positioning across a range of ceiling configurations.
