A blanking plug, or hole plug, is a component usually used to cover wiring outlets, access holes in production, or for blocking off unnecessary holes in a wall or panel. Blanking plugs are essentially used for plugging or ""blanking"" a fitting. Our range of blanking plugs from Festo which sit within the pneumatic fitting accessory area of our site has been specifically designed to blank pneumatic fittings. We stock a whole host of different types to suit your desired application, so be sure to check your blanking plug is the correct size and has the correct threaded connection.
