Silicone Pull Plugs

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

Manufactured from premium-grade silicone rubber, our pull plugs can withstand continuous exposure to temperatures up to 315°C. The parallel design allows for a secure, flush fit in threaded or non-threaded through-holes without interfering with surrounding surfaces. The integrated pull tab facilitates quick and easy removal, especially in hard-to-reach areas. Available in a wide range of diameters from 1.6mm to 25.9mm, they cater to various applications and requirements.

For applications requiring alternative designs, consider our Silicone Step Plugs, which offer similar high-temperature resistance and are suitable for masking off hard to access holes or protecting and covering a tapered hole.
