Silicone Step Plugs

Silicone Step Plugs — also known as masking plugs, high temp plugs, or masking hole plugs — are essential components for sealing, masking, and protecting holes during high-temperature finishing processes. Commonly utilised by professionals in powder coating, anodising, and painting industries, these versatile plugs ensure precision and safety by preventing contamination and ensuring clean finishes.

Manufactured from premium-grade silicone rubber, our step plugs can withstand continuous exposure to temperatures up to 315°C. The unique stepped design allows each plug to fit multiple hole sizes, providing a secure, flush fit in both threaded and non-threaded holes without interfering with surrounding surfaces. Colour-coded by size, they facilitate quick and easy identification, especially in fast-paced production environments. Available in a wide range of diameters, they cater to various applications and requirements.

For masking threaded holes consider our Silicone Thread Masking Plugs, which offer similar high-temperature resistance and are designed to fit metric thread sizes.
