PVC Connection Washer is also known as a PVC pipe washer or a PVC pipe gasket, is a small ring-shaped seal made of rubber or other flexible material that is used to create a watertight seal between two PVC pipes or fittings. It is typically used in plumbing applications, such as in the installation of pipes for drainage, sewerage, and water supply. The washer is placed between the two PVC pipes or fittings and acts as a barrier to prevent water or other fluids from leaking out. PVC Connection Washer is designed to fit snugly around the circumference of the pipe or fitting, creating a secure seal that prevents leaks.
