Ten black vinyl caps in one set: one of each size from 1/4" up to 1-1/16". Seal off every open vacuum nipple, hose barb and boost port during a boost leak test, so the air stays in the intake and you can find the leak.
Sizes included (1 each): 1/4", 5/16", 3/8", 1/2", 9/16", 5/8", 3/4", 7/8", 1", 1-1/16"
Only need one size? Each size is also sold on its own: see all vinyl cap sizes.
