Pull Plug SPP89 - .612" Hole Silicone Plug (250ct)

The SPP89 fits .612" diameter holes, close to 5/8" (.625"). The 1.000" head provides a firm grip for removal from larger bore holes. The 1.000" body length and .250" flange create full-depth sealing for heavy fabricated parts and structural components.

The .612" dimension is slightly under 5/8" (.625"). The SPP89 will seal a true 5/8" hole with light compression. If your holes measure exactly .625", the plug will fit but may be slightly loose. For tight 5/8" sealing, verify the actual measured hole diameter.

Holes in the .612" range appear on structural steel, heavy equipment brackets, large enclosures, and industrial frames. These are typically bolt clearance holes, hydraulic line pass-throughs, or cable routing holes that must remain clean after powder coating.

The SPP89 fits .612" holes while the SPP110 fits .888" holes. The SPP110 has a 1.000" head and body like the SPP89 but with a much thicker .372" flange. Use the SPP89 for sub-5/8" holes and the SPP110 for holes approaching 7/8" diameter.

The Pull Plug SPP89 (250ct) for .612" holes is priced at $108.15 (SKU SPP89). Ships in stock from Creative Coating Solutions. Clear silicone, 600F rated, 250 reusable plugs per bag. 1.000" head and body for large bore hole masking.
