These 38/400 white ribbed caps are the matching closure for our 1 gallon natural HDPE jugs and fit other bottles and jugs with a standard 38/400 neck finish. Each case contains 100 caps, the same count as one minimum order of 1 gallon jugs (25 cases of 4).

The continuous thread design twists on and off for easy resealing, and the ribbed sides give a firm grip for hand capping and opening. These caps are unlined, so they close and reseal the container but do not create a leakproof or airtight seal on their own.
