Silicone Plugs
Silicone Plugs, also known as high temperature masking plugs, silicone masking plugs or silicone rubber plugs, are essential components used to seal, mask and protect holes, threads and internal bores during powder coating, painting, anodising, e-coating, shot blasting and other industrial finishing processes. Manufactured from premium-grade silicone rubber, these reusable masking plugs provide outstanding resistance to temperatures up to 315°C whilst preventing paint, powder, chemicals and other contaminants from entering critical areas during production.
Our comprehensive Silicone Plug range has been developed to suit almost every masking application, from plain and threaded holes through to complex bores and surface masking requirements. Manufactured from durable, flexible silicone rubber, these plugs provide an excellent seal whilst remaining easy to install and remove without damaging finished components. Resistant to acids, alkalis, solvents and many industrial chemicals, they are suitable for repeated use across demanding manufacturing environments including automotive, aerospace, fabrication, engineering and general industrial production.
