Working with Compression Fittings and Tubing
Your Lift comes with a roll of ¼ inch, black, polyethylene Tubing (also called Poly-Flo® Tubing) that is
used with Compression Fittings to attach to the Air Cylinders and the Air Assist Connectors.
Note
: Compression Fittings are different from Hydraulic Fittings.
This section covers
Compression Fittings only
.
The components involved with Compression Fittings include:
8.
¼ inch, black, polyethylene Tubing
. The Air Lines require multiple Tubing pieces to make
the necessary connections. Create the Tubing pieces by cutting lengths from the long roll of
Tubing supplied with your Lift.
9.
Straight Compression Fittings
. The Air Line uses two Straight Compression Fittings, one at
the top of each Hydraulic Cylinder.
10.
Elbow Compression Fittings
. The Air Line uses two Elbow Compression Fittings, one on
each Air Cylinder.
11.
Tee Compression Fittings
. The Air Line requires three Tee Compression Fittings.
12.
Nuts, Ferrules, Rods, and Threads
. Each connector on Straight, Elbow, and Tee
Compression Fittings have a Nut, Ferrule, Rod, and Threads (see drawing below). The Nut holds
the Tubing and Fitting together. The Ferrule compresses when you tighten the Nut on the Threads
to make a secure connection. The Rod goes inside the Tubing so that nothing leaks out.
The following drawing shows the components of a connector on a Tee Compression Fitting.
Important
:
Ferrules can only be tightened once
. When you tighten the Nut on the Threads,
the Ferrule gets compressed; it literally changes shape and
cannot
be used again.
To connect Tubing to a Compression Fitting
:
1.
Push the Tubing through the Nut and over the Rod.
Do not push hard; you only need the Tubing to go a little way over the Rod. You cannot see the
Ferrule at this point, but the Tubing must go through the Ferrule and over the Rod.
2.
Slide the Nut on the Tubing
away from the Fitting
; if the Nut is still on the Threads, unscrew it
from the Threads and then slide it away from the Fitting. See the drawing above.
3.
Slide the Ferrule over the Tubing, away from the Fitting and towards the Nut.
4.
With the Nut and the Ferrule out of the way, push the Tubing further over the Rod until it stops.
5.
Slide the Ferrule and the Nut back to the Threads on the Fitting.
The Ferrule goes around the Rod and under the Threads. The Nut goes onto the Threads.
6.
Tighten the Nut.
Remember that the Ferrule can only be used once; do not tighten the Nut until everything is ready.
