AGS Sump Plug Fibre Washer is made from High-grade fibre materials that can create a light-duty seal and deliver reliable cushioning between a screw, bolt, or other fasteners.
It is also used for electrical insulation applications where little moisture is present and has good cold flow resistance.

AGS fibre washer is designed to absorb water and expand whenever water or moisture hits it, thus creating a watertight seal each and every time without cracking.
One of the biggest reasons for using fibre washers is that they typically resist corrosion and other damage when exposed to chemical agents, liquids and more.
