Pull Plug SPP33 - .225" Hole Silicone Plug (500ct)

The SPP33 fits .225" diameter holes. The 1.000" head diameter provides an easy grip surface and the 1.000" body length gives full-depth sealing. The .125" flange creates a solid surface seal to prevent powder from migrating around the plug edge.

Yes. The 1.000" body length extends deep enough to seal most through-holes in standard sheet metal and plate thicknesses. For .225" holes in material thicker than 1", the plug may not extend fully through, so verify your material thickness before masking.

One bag of 500 SPP33 plugs covers 500 holes per masking session. If each part has 4-6 holes that need masking, one bag handles roughly 80-125 parts. Reuse across multiple cure cycles extends that to several hundred parts per bag on average.

Pull plugs are primarily designed for manual installation. The SPP33 can be loaded into fixtures or jigs for semi-automated placement, but the silicone material and friction fit work best with hand installation. The 1.000" head makes manual insertion fast.

The Pull Plug SPP33 (500ct) for .225" holes is priced at $76.42 (SKU SPP33). Ships in stock from Creative Coating Solutions. Clear silicone, 600F rated, 500 reusable plugs per bag. Balanced 1.000" head and body dimensions for secure deep masking.
