Blue Anodized Aluminum Adapter (AN 806), -06 Male JIC 37 deg Flare Hex Plug

For a -06 JIC port, you're in the right place. The FBM3714 is a -06 male JIC 37 degree flare hex plug, so it threads directly into a female JIC -06 port and seals it off clean. It's made by Eaton Aeroquip and comes in blue anodized aluminum, which holds up well in typical hydraulic service. Just confirm your port is a female JIC 37 degree flare seat and you'll have a solid match.

This particular adapter is a -06, so it should fit your needs perfectly.
