This plastic syphon backnut is intended as a replacement part for securing syphons to toilet cisterns. It provides a reliable means of connecting the syphon outlet to the base of the cistern to ensure a stable fit during assembly or repair.
Supplied prepacked in a heat-sealed bag, this item is designed for straightforward handling and storage on site. It is commonly used by plumbers during maintenance or refurbishment tasks to replace existing backnuts and maintain the correct function of cistern syphons.
