This lid is made of phenolic, an industrial grade, highly rigid, plastic with a good resistance to solvents and high temperatures. Excellent for use on our amber glass boston bottles as they are highly resistant to essential oils. The cone lined cap provides a wedge type seal that not only seals across the top of the container, it also seals across the inside diameter. This liner is stress crack resistant and offers superior torque retention and excellent sealing characteristics.
4 sizes available. For the 28-400 size, please go to this page for options. Please ensure that you are matching the correct size cap to your bottle!
- ADDITIONAL SHIPPING CHARGES ON HEAVY OR BULKY ITEMS
When ordering larger amounts of packaging or quantities over 1L / kg of carrier oils or salts for shipping, we reserve the right to levy an additional ship charge (even when your order is over our $125 minimum for free shipping). These items are bulky and volumetrically heavy to ship. We will always contact you with additional shipping charges before processing your order.
