Tapered Plug vs Pull Plug
Use the hole geometry and removal workflow to decide whether a tapered plug or pull plug should be tested first.
Use tapered plugs for flexible hole ranges
A tapered plug is often the first test option for blind holes, general holes and threaded areas where the taper can seat securely across a practical diameter range.
Use pull plugs when removal speed matters
A pull plug is usually better for through holes when operators need a visible tab, stem or T-style feature to remove masking quickly after coating.
Check access and clearance
The best geometry depends on which side the operator can access, the wall thickness, nearby fixtures and whether the handling feature could interfere with the process.
Validate with adjacent sizes
For powder coating, test the selected plug after the real oven cycle and inspect retention, clean threads, removal effort and wear before approving a repeat size.
