#00 Silicone Bung / Stopper
Our #00 Silicone Stoppers provide an ultra-precise seal for openings as narrow as 10mm (bottom) to 14mm (top). Crafted in the USA from USP Class VI medical-grade silicone, these bungs are 100% non-porous and odorless. They are the ideal choice for sealing delicate laboratory vials or small-batch botanical extracts, ensuring that your samples remain pure and free from environmental contaminants.
Multiple Tooling Options: Choose from a Solid stopper for hermetic storage, a Bored version for small-scale pressure relief, or the Grab Ring for effortless removal from narrow-necked vessels.
Extreme Chemical Stability: Resistant to acids, bases, and common laboratory solvents; it will not crack, chafe, or harbor biological growth over time.
High-Temperature Tolerance: Safe for use in autoclaves and high-heat distillation setups, maintaining its flexibility and seal integrity up to 400°F.
BPA & Phthalate Free: 100% food-grade and medical-grade silicone, ensuring total safety for sensitive food, beverage, and scientific applications.
