Fitting Installation Instructions
1. Cut the tube off squarely next to the hose ftting. At least 7/8”
straight length is required and the outside diameter of the tube
should be smooth and free from deep lengthwise scratches.
2. To prevent cutting the inside of the O-Ring, smoothly chamfer
the outside diameter of the cut end 15° to 30°. Deburr the
inside diameter.
3. Remove the nut, compression sleeve, and O-Ring from the
ftting and lubricate the O-Ring with a lubricant that is
compatible with the refrigerant used in the system.
4. Place the lubricated O-Ring in the counterbore of the ftting.
5. Slip the compression sleeve, small end, into the nut and
assemble the nut on the ftting fngertight. Make sure the
compression sleeve is not cocked in the nut. Back the nut off
1/6 to 1/3 turn (one to two hex fats).
6. Insert the chamfered tube end through the nut into the ftting.
If high resistance is felt when the end of the tube contacts the
O-Ring, remove the tube. The end of the tube may require a
large chamfer and/or the O-Ring may require more lubrication
on the inside diameter. Repeat the previous steps.
7. (a) Make sure the tube is bottomed in the ftting
(b) Tighten the nut fnger tight
(c) Mark the ftting and nut hex indicating the starting point
(see illustration) and
7.
(d) Wrench tighten the nut 1 to 1-1/6 turns (6 to 7 hex fats).
8. Later, if it is ever necessary to loosen the connection,
re-assemble the nut 1/6 turn (one hex fat) after fnger tight.
