Silicone Ribbed Plugs

Silicone Ribbed Plugs — also known as silicone stoppers, or flangeless silicone masking plugs — are essential components for sealing, masking, and protecting 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 ribbed plugs can withstand continuous exposure to temperatures up to 315°C. The ribbed, flangeless design allows for a secure, flush fit in threaded or non-threaded holes without interfering with surrounding surfaces. Available in a wide range of diameters from 2mm to 31mm, they cater to various applications and requirements.

For applications requiring tapered designs, consider our Tapered Rubber Plugs, which offer similar high-temperature resistance and are suitable for different masking needs.
