Ot Header ?

[hickz3]

We're currently installing a set of Rewarder OT headers on a buddy's boat and can't find the right fitting for the water lines going to the headers. It appears to be a 1/2" JIC fitting, no problem, but I can't seem to locate a fitting with an end that will fit the 5/8" water lines. Not running stainless lines as of yet with AN fittings.
Any help would be appreciated.

1/2" Lines Are Plenty Big To Run To Your Headers. Probably Easier To Find Those Fittings.
