Product details· 02

How it is made & specified.

This silicone masking cap covers a bolt, stud, or protruding thread during coating, protecting the mating surface from powder, paint or plating buildup. It is rated for standard bake and cure cycles without softening or losing its grip on the fastener.

Caps work where a plug alone cannot help - covering an external protrusion rather than sealing an internal bore. Match the internal cap diameter to the fastener or stud size for a snug friction fit; a loose cap can let coating material creep underneath during spray or dip application.

Like other silicone masking components, this cap is reusable across multiple coating cycles. It can be supplied loose in bulk or kitted alongside matching plugs and tape for a specific part number.

FAQ· 06

Red Silicone Masking Cap questions.

What's the difference between a masking cap and a masking plug?

A cap covers an external protrusion like a bolt or stud; a plug seals an internal hole or bore.

How do I size this cap correctly?

Match the cap's internal diameter to your fastener or stud size for a snug friction fit that won't let coating creep underneath.

Can this cap be reused?

Yes, it's designed for repeated coating cycles rather than single use.
