The air-tight seal ensures that there is absolutely zero chance of leakage when the cap is adequately tightened. The professional quality of these caps means that there's zero chance of any liquids evaporating or becoming contaminated by outside sources. Pairing this cap with any of our range of bottles that share the same closure size ensures that you're getting value for money and premium quality safety.

Our various V#’s are to differentiate between our many suppliers. The only differences you will see in different V#’s will be slight cosmetic changes, sometimes unnoticeable, as well as slight differences in shape/sizing (in regards to bottles). However, all products of the same type will function the same. If you have any other questions,just let us know!
How do I choose the correct closure size?
Closure sizes are expressed using two different numbers.
The second number is the Glass Packaging Institutes (GPI) thread finish and refers to the height of the cap and the style of the threads on the closure or bottle.
