"Thread Length" same as "Inside Bore Size"?

[Ravynmagi]

I think I need some 4mm thread length barbs for my Koolance 487x2 block.

I'm trying to figure out what the thread length is on these Primochill barbs.

The specs have something called "Inside Bore Size" which is "0.40"

I'm hoping that means the same as a 4mm thread length. Not sure of their terminology though.

Inside bore size sounds more like the inner diameter of the actual barb and seeing that it measures .40in, appears to be the logical conclusion for a 1/2 barb. I may be wrong, but don't all G-1/4" threaded barbs share the same thread length? Hopefully someone with more experience will chime in.

Per Koolance :

Nozzle threading is standard G 1/4".

Per Primochill ad at the link you provided.
Thread Size - G 1/4


The Primochill barbs should thread and seal properly on your block - the thread size and the type of threads are a match.

Edit:
at 25 cents for a couple of extra O rings, thats well worth grabing some extra ones if you order those barbs. (which seem really nice).
