Silicone Plugs With Handle

Tapered Silicone Plugs with Handle — also known as silicone masking plugs or high temp silicone plugs for powder coating — 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 tapered plugs with handle can withstand continuous exposure to temperatures up to 315°C. The tapered body allows for a secure, flush fit in threaded or non-threaded holes without interfering with surrounding surfaces. The addition of a moulded silicone handle allows for fast and safe removal by hand — especially useful in production settings where speed and convenience are critical, or when access to the plug is restricted. Available in a wide range of maximum diameters from 4.8mm to 56mm, they cater to various masking requirements across industries.

For alternative plug styles, consider our Silicone Ribbed Plugs, which offer similar high-temperature resistance and enhanced grip through a ribbed body profile.
