38-400 Black Ribbed Phenolic Cap with Cone-Shaped Insert, Each
38-400 Black Phenolic caps with Polyseal cone liners form an exceptionally tight seal and offer a good chemical barrier. This liner molds itself around the sealing areas of the finish as the cap is screwed on, virtually eliminating leakage, evaporation, contamination, binding and backing off. Great for everything from liquids, to soaps, to macro-invertebrates.
Typically ships from Pennsylvania.
