The PVC 3-in-1 connector Ø 20/18/16 TS11126003 is designed for air conditioning users who need a reliable and practical solution for connecting pipes of different diameters. It is particularly suitable for installation and service tasks, where the correct arrangement and connection of pipes of different dimensions is key.
