This is a 40 gallon vertical compressor with the electric motor and compressor mounted at the top of a 40 gallon storage tank. A piece of 3/8" copper tube with a female compression fitting at either end conducts to male fittings at the compressor and at the storage tank. This tube conducts the compressed air from the compressor to the storage tank where it remains until called for.
Problem: The brass female compression fitting connecting the copper tube to the compressor had split at the male fitting on the compressor..
1.Unplugged compressor.
2 Loosened female compression fitting nut at top end of copper tube from male compressor unit fitting.
3. Loosened female compression fitting nut at bottom end of copper tube from male tank fitting.
4. Removed copper tube from compressor tank & compressor unit.
5. Removed both female compression fitting nuts from copper tube.
6. Placed new female compression fitting nut on copper tube
7. Placed old, existing female compression fitting nut on copper tube.
8. Wrapped both male fittings (on the compressor & tank fittings) with Teflon tape.
9. Replaced copper tube on compressor unit & tank.
10. Tightened female compression fitting nuts.
11. Plugged compressor in.
Voila!

Quick and easy call with the model number of my old Campbell Hausfield compressor took 10 minutes to have parts on the way for 15 bucks or so. Once receive removed the nuts securing both ends of the failed pipe and installed new pipe/seals/nuts. Compressor holds 120PSI again.

Removed of line and installed new tube with 2 compression rings. Had ordered extra compression ring due to confusing break down on picture of parts used to select parts.
Simply removed old line, slid compression rings on new tube, cut tube to proper lenghth, and tightened the copper nuts onto compression rings. Surprised by the fact that the tube was too long. Works perfect.
