AN Hose Assembly Instructions
1 | CUT HOSE TO SIZE
To minimize braid flare while cutting, wrap hose with tape. Cut the hose to length using large bolt cutters, a fine-toothed hacksaw, or a cutoff wheel.
2 | INSERT HOSE IN SOCKET
Remove the tape then insert the hose into the socket by pushing and twisting the socket counter-clockwise.
3 | MARK THE HOSE
Mark the hose at the rear of the socket with tape or a marker. Use this mark to ensure the hose does not back out during assembly.
4 | LUBRICATE FITTING AND HOSE
Lubricate the inside of the hose and the fitting nipple threads with engine oil.
5 | TIGHTEN FITTING IN VISE
Insert the fitting nipple in the socket, engage the threads and screw in by hand. Tighten with a wrench while ensuring the hose does not back out of the socket. TIP: Use an aluminum AN wrench or wrap the fitting in tape to avoid damage.
6 | INSPECT AND TEST ASSEMBLY
The maximum gap between the socket hex and the fitting nipple hex is 0.03 inches. Check the mark made in Step 3 to verify that the hose did not back out from the socket. Clean and inspect, then test for leaks at twice operating pressure before use.
