Masking Caps

Protective masking caps engineered to cover external threads, studs, shafts, and
pipe ends during surface finishing operations. Manufactured from flexible silicone
and vinyl materials, our caps provide tight seals to prevent coating build-up on
critical mating surfaces. Features easy-peel designs for fast removal even with
gloved hands. Standard sizes fit M3-M24 threads and 1/8″ to 3″ OD tubes.
