Male Orfs X Female Jis

Description & Features

Manufactured from steel in a straight configuration, this Adaptall adapter connects a 1/4" male ORFS port (9/16-18 UNF thread) to a 1/4" female JIS port (G 1/4-19 thread), making it a practical solution for bridging two common but incompatible hydraulic thread standards. The Male Orfs X Female Jis measures 32.8mm in length with a 19mm CH width, fitting cleanly into space-constrained installations.

Adaptall's interchangeable adapter system is widely used in hydraulic circuits where field assembly or system reconfiguration requires reliable thread conversion without custom fabrication. The steel construction suits standard hydraulic service conditions across mobile and industrial equipment.

Question by: Stan A on Mar 9, 2026, 8:32 AM
Does this thing actually bridge ORFS and JIS ports, or do I need some kind of intermediate fitting to make that work?
Answer by: Customer Support on Mar 11, 2026, 7:34 AM
Straight conversion, no intermediate piece needed. One end is a 1/4" male ORFS with a 9/16-18 UNF thread, the other is a 1/4" female JIS running G 1/4-19. You thread the ORFS side into your JIS port and you're done. Steel construction, straight configuration, 32.8mm long so it keeps the overall hydraulic connections fairly compact even in tighter spots.
Question by: Wade G on Feb 5, 2026, 7:09 AM
got a hose end that’s 9/16-18 ORFS male, will this adapter let me hook it into a G 1/4-19 JIS female port?
Answer by: Customer Support on Feb 7, 2026, 6:10 AM
Functionally, it is a straight thread adapter that converts between those two standards: one side is 1/4 inch male ORFS with a 9/16-18 UNF thread, and the other side is 1/4 inch female JIS with a G 1/4-19 thread.

So, this here adapter... it'll let me hook up a Japanese fitting to a US one? Just want to make sure before I order it.
Answer by: Customer Support on Apr 8, 2026, 6:29 AM
Functionally, yes, this adapter allows you to connect a 1/4" male ORFS port (common in the US) to a 1/4" female JIS port (found on some Japanese equipment).
