Cone Lined Caps

PE Cone Lined Caps 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. These caps are made of phenolic plastic and have an internal polycone liner, which is made of an oil-resistant plastic and offers excellent chemical resistance.
