SKU: GB40-022-400 / Black (Ribbed Skirt) (6000)

Our PP Black Phenolic Cap features a PP(Polypropylene) Polycone liner. These durable Semi-Ribbed Phenolic plastic caps have high tensile strength and are made to be durable. For instance, Phenolic Caps are mainly used in environments that use corrosive chemicals and liquids. This makes it an ideal closure to handle against aggressive products that contain hot temperatures and acids.

Above all, our Phenolic Cap comes with a natural-colored PP Polycone liner. Therefore, this Polycone liner is cone-shaped and placed inside the cap. Once on the container, this liner acts as a wedge that seals the top of the cap with the neck diameter. This creates a tight seal on the bottle to trap out oxygen and prevent leakage. In addition, Polypropylene has great heat resistance with an extremely high melting point of (320 degrees Fahrenheit or 160 degrees celsius)

This item has a 22-400 neck finish. For instance, the first number refers to the diameter (in mm), and the second refers to the closure depth, style, and thread.

In conclusion, This top is a good fit for any of our 4 oz (120ml) Boston round glass bottles and is great for a variety of uses from aromatherapy and essential oils to vape juice. Pair this dropper with one of our great “Matching Products” below.
