Workshop Practice with Hose Adapters
Students fit the adapter to the 5/16 in service port of the R-32 Split Air-Conditioner. A 1/4 in Refrigerant Hose then runs from the adapter to one of the Small Vacuum Pumps. The unit can then be evacuated without a dedicated 5/16 in hose.
Teachers can use the adapter to explain why the two port sizes exist. Every hose and gauge on the line must still suit the higher pressures of R-410A and R-32. Before each use, students check that the flare faces are clean and free of nicks.
Frequently Asked Questions
Which way round does the adapter fit?
The 5/16 in female end screws onto the male service port of the system. The 1/4 in male end then takes the female nut of a standard 1/4 in hose, so hoses with 1/4 in ends can reach R-410A and R-32 ports.
What pressure is it rated for?
It is rated for 1000 psi working pressure. The hoses and gauges on the same line must also be rated for the refrigerant in use, since the lowest-rated part sets the limit for the whole connection.
Does it need thread tape or sealant?
No. Thread tape is not used on flare fittings. The seal forms on the flare face, or on the gasket inside the hose nut, so a hose nut is normally tightened by hand. Replace a hose gasket that is flattened or split.
Why are refrigeration adapters made of brass?
Brass machines cleanly, does not rust and seals well against copper and brass flare faces. It is the usual material for service fittings on refrigeration and air conditioning work.
