Yea, some are -6AN and some are -8 AN

 

[laocivic]

one hybrid and one p2r

-6 and -8 is the size of the flared end for the hose. the end that tightens into the rail would be 3/8" or 1/2" pipe thread im assuming.

ok rail is -6 what size fittings for my setup not?? i need a fitting for the Rail > hose that goes to filter...and rail > hose that goes to regulator..i would assume they're the same

I have yet to see a K series rail that uses pipe thread. Almost all of them (including ours) uses a -8 AN fitting with an o-ring (also known as an ORB fitting).

They are not pipe thread.
