Product family
Silicone Masking Plugs
A starting point for holes, bores and threaded areas that must stay clear through industrial finishing.
Selection starts with the part and process.
Send the hole diameter, depth, process, temperature cycle and quantity. We will recommend the most suitable plug style and an adjacent-size sample range when appropriate.
Use this product family when
You need to compare several plug styles before a bulk purchase.
The feature is a hole, bore, thread or no-coat area in an industrial finishing process.
The buyer can provide measured geometry and process details for a sample-first review.
Do not use it as the first choice when
A same-day domestic stock purchase is the main requirement.
The application has chemical or temperature exposure that has not been shared.
The no-coat area requires a dedicated custom geometry from the start.
Measurement checklist
Send these inputs with the RFQ so the first response can focus on a testable size or custom review path.
| Hole or bore diameter | Actual measured diameter, not only nominal thread size |
|---|---|
| Depth and access | Blind, through, counterbore or limited-access detail |
| Process cycle | Powder coating, e-coating, anodizing, plating or other exposure |
| Decision goal | Sample fit, replacement sourcing, custom review or repeat order |

Frequently asked questions
How do I choose a masking plug size?
Start from the actual hole diameter and masking depth, then test the selected fit in the real process before a production order.
Can you cross-reference an existing part?
Yes. Send the current part number, a photo or a drawing together with the process details and we can suggest a fit-for-test option.
Need to confirm fit first?
Request a sample range around your measured size.
Samples can be scoped around actual process, dimensions and testing goals before a bulk order.
