Silicone Tapered Plugs
Silicone Tapered Plugs also known as silicone stoppers or silicone tapered bungs 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 rubber bungs ensure precision and safety by preventing contamination and ensuring clean finishes.
Manufactured from premium-grade silicone rubber our tapered plugs can withstand continuous exposure to temperatures up to 315°C. The tapered 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 with maximum diameters from 1.6mm to 127mm they cater to various applications and requirements.
For applications requiring alternative designs consider our Silicone Ribbed Plugs which offer similar high-temperature resistance and are suitable for different masking needs.
