Miscellaneous Silicone Plug Starter Kit

The kit includes 21 different types and sizes of silicone plugs designed to cover the most common masking needs. This variety lets you test which sizes fit your specific parts before committing to bulk orders of individual sizes. Each type addresses different hole shapes and thread sizes.

The plugs are rated from 0 to 600F (315C). This covers standard powder coating cure temperatures of 350-450F with significant headroom. The silicone material maintains its shape, flexibility, and masking seal at sustained cure temperatures without melting, outgassing, or leaving residue.

The plugs mask lead-in threads, grounding points, holes, and surfaces during powder coating, e-coating, painting, anodizing, and plating processes. They prevent coating material from entering areas that must remain clean for assembly, electrical contact, or threading after the finishing process.

Yes. Silicone masking plugs are designed for repeated use across multiple coating cycles. After each cycle, pull the plug out and inspect for damage. Most plugs last dozens of cycles before the silicone degrades. The starter kit lets you evaluate durability for your specific cure profile before bulk ordering.
