Pull Plug SPP437 - .437" Hole Silicone Plug (250ct)

The SPP437 fits .437" (7/16") diameter holes. The 1.500" head and 1.500" body are the largest dimensions in the standard pull plug range. The .300" flange provides the thickest seal of any plug in the lineup for maximum surface coverage.

Larger pull plugs use more silicone per piece, so the SPP437 ships in 250ct bags to keep pricing practical. The .437" plug with its 1.500" head and body is significantly larger than the 500ct plugs. A 250ct bag still covers substantial production runs.

Blue designates the .437" (7/16") hole size. The bright blue color stands out on metal parts and is easy to spot during post-cure plug removal. Color coding across the full lineup prevents size confusion, especially when multiple plug sizes are used on the same part.

The SPP437 body extends 1.500" into the hole, the deepest insertion of any standard pull plug. This makes it ideal for through-holes in thick material, manifold ports, and deep bores that need complete sealing against powder entry from the front or back side.

The Pull Plug SPP437 (250ct) for .437" holes is priced at $61.57 (SKU SPP437). Ships in stock from Creative Coating Solutions. Blue silicone, 600F rated, 250 reusable plugs per bag. 1.500" head and body for deep sealing of 7/16" holes.
