LEAKS, RE-USE

LEAKS:
If it leaks, it has probably been assembled incorrectly or the sealing surfaces on the adapter and the nipple have been damaged—or just possibly someone has attempted to assemble an AN 370 seat hose end into a 450 SAE cone.  Damage to the cone or the seat can be caused by a multitude of sins—dirt and over tightening being the most common.

RE-USE:
All of Earl’s removable hose ends are completely reusable, as is the hose and as are most of the competing brands.  As usual, Earl’s have an edge.  When disassembling a nipple and cutter type hose end, it is very common for the inner tube of the liner, which is captured between the nipple and cutter, to be torn off and to remain in place.  If this happens, the rubber must be removed before the hose end can be reused—and it is a bear to get out.  With SWIVEL-SEAL the chances of this happening are greatly diminished because the cutter can rotate with respect to the nipple so that the rubber is faced with only one moving surface. 

The procedure is as follows: 
     Place the socket in a vise, and with a wrench on the nipple and another on the cutter, hold the nipple and turn the cutter until the socket is disengaged.  Then pull the hose off the nipple.  This method will only work with the angled SWIVEL-SEALS.  With the straight hose ends, you can either, hold the socket in the vise and turn the nipple or you can remove the cutter from the nipple.  All parts of the SWIVEL-SEAL are ready for reuse as soon as they have bee cleaned and re-lubricated.
