STP103 Tapered Silicone Plugs – Reusable High-Temp Masking Plugs

The STP103 is a reusable, high-temperature tapered silicone masking plug used in powder coating, sandblasting, and industrial finishing. Its tapered profile seals holes and ports without adhesive, protecting surfaces from media and coating overspray during production operations.

The STP103 is a mid-range tapered plug (part series SKP1055) designed to fit and seal standard bore diameters in its size class. For exact diameter specifications, refer to the product listing or contact Creative Coating Solutions for a size chart.

The STP103 silicone plug is rated for continuous high-temperature service up to approximately 400°F (204°C), making it compatible with standard powder coating cure ovens and industrial spray finishing systems.

Yes. The STP103 is a universal tapered silicone masking plug that works across all brands of powder coating ovens, blast cabinets, and industrial finishing equipment. It is not proprietary to a specific machine or manufacturer.

Press the tapered small end of the STP103 into the bore or port you need to protect. Hand pressure locks the plug firmly in place. After the coating or blasting process, pull the plug free and inspect for wear before reuse.

The STP103 is suitable for any blast cabinet, powder coating line, or industrial finishing operation requiring a mid-range tapered silicone plug. It is brand-agnostic and fits standard production masking workflows.
