Global TTC 1 & 2 Wire Braid Steel Crimp Fitting, 9/16-18 Male O-Ring Face Seal, -04 Hose, Straight

For a straight crimp fitting on -04 hose with a 9/16-18 male O-Ring Face Seal (ORS) thread, this matches that setup. It is a TTC steel crimp fitting intended for 1 and 2 wire braid hose.

For O-ring face seal connections like this one, thread sealant isn't just unnecessary, it can actually work against you. The seal comes from the O-ring itself making contact with the flat face of the mating port, not from anything on the threads. Applying sealant can interfere with that metal-to-face contact and cause more problems than it solves. So yes, skip the sealant on this one.
