Silicone Thread Masking Plugs

Silicone Thread Masking Plugs — also known as threaded masking plugs, or silicone thread protectors — are essential components for sealing, masking, and protecting threaded 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 thread masking plugs can withstand continuous exposure to temperatures up to 315°C. The design allows for a secure, flush fit in threaded holes without interfering with surrounding surfaces. Available in a wide range of sizes from M3 to M30, they cater to various high temperature industrial applications and requirements.

For applications requiring both internal thread protection and external surface masking, consider our Silicone Washer Plugs, which offer a built-in washer flange for precise coverage around the hole face as well as inside.
