JIC 37° and SAE 45° Flare
Parker’s recommended assembly method for JIC 37° fare and SAE 45° fare is the Flats From Wrench Resistance
(FFWR) method. This includes steel as well as other materials.
The torque values assigned by size are for reference only, and are only applicable to Parker system components using
the FFWR method with trivalent chromate passivation on zinc plating of carbon steel components without lubrication.
Seal-Lok
Note: The assembly torques listed are higher than the test torques published in SAE J1453.
Torque Conversion Equivalents
The torque values for other materials are as follows:
• Brass fttings and adapters - 65% of the torque value for
steel.
• Stainless steel, and Monel - Use 5% higher than listed for steel.
Threads to be lubricated for these materials. .
• Dissimilar metals - use torque value designated for the
lower of the two metals.
• All fttings are dry except as noted above.
The Flats From Wrench Resistance (FFWR) and torque values listed
above are consistent with the values recommended by Parker Tube
