Diffuser Caps

Select your product


Matching Neck Threads

Not every diffuser cap fits. The threaded neck finish of the cap has to match the threaded neck finish of the glass product you choose. That means both items (glass and closure) should have the same numbers. But what do the numbers mean? Well, take 24/410 as an example: the first number refers to the neck finish diameter, while the second, to the height and style of thread.
