Product Questions & Answers

trying to hook up a #4 ORFS hose end to a #4 JIC line, is this the straight adapter for that?
Question by: Scott B on Jan 14, 2026, 6:21 PM
For connecting those two styles, it matches a 9/16-18 female O-ring face seal on one side to a 7/16-20 male JIC 37 degree flare on the other, in a straight body. It is commonly labeled as #4 FORS x #4 MJ.
