AN Fitting Tightening Torque Chart

 

 

Here is a list of torque values for each AN fitting size.

Note: 12 inch-pounds = 1 foot-pound

AN Size	Aluminum Fittings		Stainless Steel Fittings
	in.-lbs.	ft.-lbs.	in.-lbs.	ft.-lbs.
-02	50-80	-	75-120	-
-03	70-105	-	95-140	-
-04	100-140	-	135-190	-
-05	130-180	-	170-240	-
-06	150-195	-	-	18-23
-08	-	22.5-29	-	39-45
-10	-	30-36	-	51.5-62
-12	-	38-46	-	71-88
-16	-	58-70	-	95-114
-20	-	71-85	-	126.5-152
-24	-	75-90	-	158-190
-32	-	150-166.5	-	188-245

Assembly Notes

• These torque values do not apply to flared tube or compression fittings.
• For best results, torque to the smaller number in the torque range, and tighten until it stops leaking (without exceeding the max torque).
• DO NOT mix 37-degree flared AN fittings with different flare-type fittings. This will cause damage and potential leaks.
• Be sure to double check dimensions when using another brand's fittings with Raceflux hoses or vise versa.
• The conversion for all AN fittings to their nominal inch size is the AN number divided by 16. For example: -8 AN = 8/16″ or 1/2″.
