STP0 Tapered Silicone Plug – High-Temp Masking for Powder Coating

The STP0 is a high-temperature tapered silicone masking plug used to seal holes and threaded ports during powder coating, e-coat, and anodizing. Its flexible silicone body grips the bore wall and withstands oven cure temperatures, keeping critical surfaces clean and coating-free.

STP0 tapered silicone plugs are rated to withstand continuous high-temperature oven cure cycles, typically up to 500°F (260°C), matching the requirements of standard powder coating and liquid paint cure schedules without melting or deforming.

The STP0 is designed for slightly larger openings than the STP00, accommodating small-diameter holes in the range of approximately 1/4" to 3/8" depending on insertion depth. Its tapered geometry self-aligns with the bore for a snug, leak-proof seal during the coating process.

Press the STP0 small-end first into the hole before racking parts for coating. The taper expands to grip the bore wall, preventing overspray from entering. After the cure cycle cools, pull the plug straight out - it releases cleanly with no adhesive residue, leaving a paint-free surface ready for hardware installation.

The STP0 is widely used in automotive OEM and aftermarket finishing, agricultural equipment, aerospace component coating, and contract powder coating job shops. Any application requiring reusable masking of small bores while maintaining tight dimensional tolerances benefits from this plug.

The STP0 fits slightly larger holes than the STP00 and smaller holes than the STP100, making it a mid-step in the small-diameter range of the STP series. Selecting the correct plug by hole diameter ensures a leak-proof seal and prevents plug blow-out during the cure cycle.
