What Does 89-100 closure cap mean – 63-410 Meaning

So you want to know the meaning of a cap size.  I’ll explain what an 89-100 , 89-410 , 69-400 and 69 -410 means in simplest terms I can think of.

I admit, I am not a packaging engineer but we work with these caps fairly frequently and I can give you a good idea what each of these sizes mean.

This isn't meant to describe every cap size but I figure the 89 sized closure is fairly unusual for caps meant for bottles / jars so there might be good folks (like you) out there wanted to know what these designations mean.

We typically work with polyethylene bottles and their respective closures but this info should work for other closures as well.  As usual, double check with you cap manufacturer if you aren't sure or want to double verify.

Anyway…..

The first number designated on a closure is the cap diameter in millimeters.  Millimeters whether in the USA or abroad is the standard measurement used for caps.   So in this case the 89 means 89mm and the 63 means 63 mm in diameter respectively.

The second number represents the rotations.  This is less intuitive. The 400 means one complete rotation is required to fully seal the cap. If you want to get technical there is also a required torque pound measurement related to the diameter but in layman's terms, 400 means you’ll be able to turn the cap 360 degrees before you can’t turn it anymore.

410 means you’ll get one and one half ( 1  ½) turns before it fully screws down on the bottle.

Another way to think of it is you’ll have to screw the 410 cap down further (more rotation along the thread) than a 400.

So……

63-400  = 63 mm in diameter and you’ll turn it a complete 360 degrees give or take to have it close.  

63 -410  = 63 mm in diameter and you’ll turn it a complete 540 degrees or 1 ½ rotations give or take to have it close.  

89-400 = 89mm in diameter and you’ll turn it a complete 360 degrees give or take to have it close.  

89-410 = 89mm in diameter and you’ll turn it a complete 540 degrees or 1 ½ rotations give or take to have it close.  

Of course you’ll want the neck of your bottle/jar to match the size of the cap as well.
