Plastic PP Bracket

As an installer you want to be sure that the bracket has been installed in a correct way which means tight enough around the socket or the spigot. When the bracket is applied around the socket of the pipe or bend, you fix this bracket with 1 click, whereas if the bracket is mounted around the smaller diameter of the spigot, you fix the bracket in 2 clicks, thus allowing the expansion of the flue gas system. This combination ensures that the pipes and bends cannot disengage due to expansion and contraction. read more


All plastic, including PP, expands by heat. To ensure the installation stays totaly gas tight, use the Cox Geelen mounting bracket. To install this bracket correctly, the assembly instructions (to be downloaded from www.coxgeelen.com/download) must be followed. Only in this way, Cox Geelen guarantees a safe and flue gas tight installation. We strongly recommend using only Cox Geelen products and no to mix materials.
