Before starting work assemble you will need safety glasses, correct spanners, grinder with cut off wheel, tape measure soft jaws for vice, air and grease.

What to check

Check hose length to ensure you have sufficient hose for hose assembly. Apply clean grease to inside and outside of hose. Take first body and using soft jaws firmly clamp in vice. Body has an internal left hand thread.

If hose is too hard to turn by hand carefully clamp hose in vice and turn body with wrench (spanner). Ensure hose has bottomed out at base of body. Unscrew in clockwise direction half a turn.

Follow these steps

Now remount in vice with exposed thread of body pointing up. Lubricate body then the threaded hose tail. After that make sure youre using the correct size wrench screw hose tail into body and hose assembly in a clockwise direction.

Remove complete assembly from vice. Mark hose to your desired assembled length.

In this example the assembled hose length will be 800mm (31-1/2 inches) Line up the end of the hose fitting with the marked end of the hose, then lay body against the end of the thread.

Mark hose 12mm (1/2″) behind the body. You need to imagine that the body, hose tail and hose are already assembled.

Put hose in vice and carefully cut hose on the second mark you have made.

Use angle grinder with metal cutting disk. While cutting apply slight pulling tension to end of hose. Carefully cut hose squarely.

Clean out hose with compressed air to remove all abrasive particles from inside of hose. Put second body in vice and repeat as earlier. Remember to screw hose in an anti-clockwise direction.

Make sure hose bottoms out at base of body and then back off half a turn clockwise. Lubricate hose tail and exposed thread on body with grease.

Assemble with correct wrench (spanner). Blast hose assembly clean with compressed air Check finished assembled length. Pretty good 31-1/2 inches! (800mm)

This next gauge will read to 8000 PSI, if you’re testing to 4000 it’s better to get a gauge that reads double what you want to test to.


So we’ll test to 4000 PSI on this 8000 PSI gauges. What we do here is add the adaptors such as this tee to be able to connect it to a pressure generating device as well as a pressure gauge. Here we are connecting the pressure supply.

And here we’re connecting up the pressure the gauge. This pressure generator converts 100 PSI of air up to 10,000 PSI of Oil Pressure. Pressure test to 4000 PSI to test strength of connection.
