Speargun Muzzle Adapters for Rubbers

 

How to Measure: 

ADAPTER Thread SIZE NOTES and Comments:

There are lots of mis-information on thread sizes vs rubber tubing OD's out there in Forums and Dive sites. This Part is made to be a True 14mm-1mm Thread Class 6g.

The Female threaded hole on your muzzle should measure around ~13mm (e.g. a 12.9 - 14.1mm solid Pin should just fit inside the internal threads). 

If your threaded muzzle hole measures ~15mm, then you most likely need a 16mm-1mm Adapter, and NOT this part., See other Adapter 16mm-1, B3017-1.

I've seen Muzzles and band call out for "16mm threading".  This jargon is totally misleading and confusing.  I purchased one of these muzzle parts to verify what that term meant and it is a 14mm-1 thread that I measured.   

My only thought on this confusing language is from the Rubber Tubing OD size of 16mm, then it is assumed to be "16mm threading". Yes, I Rolled my Eyes too.  |o)
