Silicone caps (SC's) are the most cost effective product to cap threads, studs
and tube ends that must be masked and heated from 350 to 600°F. Turned around,
they can be ‘nosed in’ to straight-walled holes and function as a plug too.
When using as a Silicone cap, the ID of the cap should be 2% to 5% smaller
than the thread or stud. In larger sizes, 0.015" to 0.020" may be appropriate instead.
When using as a Silicone plug the OD of the cap should be 4% to 7% larger
than the hole diameter. In larger sizes, 0.015" to 0.020" may be appropriate instead.

HINT: To release trapped air from larger parts when heated for powder
coating, pierce a small hole in the end of the cap with a finishing nail or scissors.
This will help air to "burp" out when heated, and avoid "blow offs"
of caps during the cure cycle which can damage surface finishes.

SC's are ideal for use in powder coating, e-coating, plating, and
anodizing.
- SC's offer excellent high heat and good chemical resistance.
