Lab Exercises on High-Pressure Units
On the R-410A Split Air-Conditioner and the R-32 Split Air-Conditioner, students connect a hose to the 5/16 in service port. With the unit off, they read the standing pressure. With the unit running in cooling, they note how far the readings sit above those of an R-22 or R-134a system.
Teachers can lay this set beside the 150 cm Refrigerant Hose set, which has 1/4 in fittings and a 600 psi rating. Students then match each set to the refrigerants it suits by fitting size and pressure rating.
Frequently Asked Questions
Why do these hoses have 5/16 in fittings?
R-410A and R-32 equipment uses 5/16 in service ports, a different size from the 1/4 in ports on older R-22 and R-134a systems. The change keeps lower-rated tools off high-pressure systems, and these hoses suit the larger port.
What does the 800 psi rating mean?
It is the pressure the hoses can carry in normal use. R-410A and R-32 run well above R-22 pressures on the high side, so their hoses need a higher rating than the 600 psi of common 1/4 in sets.
Can the set be used on R-22 systems?
It can carry R-22 pressures, but R-22 units usually have 1/4 in ports, so an adapter would be needed. Many workshops keep separate hose sets for each refrigerant group so that oils and refrigerants are not mixed.
Why do the gauges show no pressure when the hose is on the port?
The valve core in the port is probably not being pushed open. Most charging hoses carry a small core depressor in one end only, and that end must go on the service port. Fitted the other way round, the core stays shut and the gauge reads nothing. Retire any hose that shows a bulge or a crack.
