Click Seal is a unique range of flexible toilet and tap connectors from Fluidmaster. Over tightening connections can result in leaks and damage, the Fluidmaster Click Seal eliminates this problem entirely. The Click Seal end can be tightened by hand until an audible “click” sound is heard. This provides a perfect seal and can not be tightened further. This version is 500mm in length and offers a stress free installation solution.
