Lab Exercises with the 36 in Hoses
On a refrigeration trainer, students run the red hose from the high-side service port and the blue hose from the low-side port. Both go to the matching sides of the Manifold Gauges For Refrigeration Systems, which also use 1/4 in hoses. The yellow hose joins the centre port to the 1/4 in inlet of one of the Small Vacuum Pumps. Students evacuate the circuit and watch the low-side compound gauge fall below zero.
After charging, students brush Bubble Solution For Leak Detection on each flare joint and watch for bubbles. Because these hoses have no ball valves, a little refrigerant escapes each time a hose is taken off a port under pressure. Teachers can use this to show why valved hoses and short hose runs cut refrigerant loss.
Frequently Asked Questions
Which colour hose goes where?
The red hose joins the high side of the system to the high-pressure side of the manifold. The blue hose joins the low side. The yellow hose is the service line from the centre port to a vacuum pump, a refrigerant cylinder or a recovery machine.
How is this set different from the valved hose set?
These 36 in hoses have plain ends. The longer Refrigerant Hose set has a compact ball valve on each hose, so a line can be shut before it is disconnected. Less refrigerant escapes and less air gets into the hose.
What does the 600 psi working pressure mean?
It is the highest pressure the hoses are meant to carry in normal service. Compare it with the highest running pressure of the system before you connect, and use these hoses only where the system stays below it.
Why does a hose leak at its fitting?
The usual cause is the rubber gasket inside the hose end. It wears, cracks or flattens with use and then no longer seals on the port. Fit a new gasket, tighten the nut by hand and check the joint with bubble solution. Keep the ends capped and avoid sharp bends and long spells in the sun, which harden the hose.
