EPDM Caps (EC's) are the most cost effective product to cap threads, studs
and tube ends that must be masked and heated from 200 to 350°F. Turned around,
they can be ‘nosed in’ to straight-walled holes and function as a plug too.
When using as an EPDM cap, the ID of the cap should be 2% to 5% smaller
than the thread or stud.
When using as an EPDM plug the OD of the cap should be 4% to 7% larger
than the hole diameter.

HINT: To release trapped air from larger parts when heated for paint
cure cycles, 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.
- EC's are ideal for use in wet spray painting, plating, and anodizing.
- EC's offer excellent chemical resistance.
