Very flexible, brown, silicone drip tubing which can be squeezed shut or opened by the Tropf-Blumat valve, serves as a small supply tube for single pots or container (tub) plants or as intermediate pieces in a series of drippers. Mini-branch connector for the drip tubing allows, for example, one water supply tubing to be shared by adjacent pots each with it�s own Tropf-Blumat.
