Question

R-410A requires a high-pressure manifold gauge and hose set. They must have a: _________.

a) 2000 psig burst pressure and 400 psig working pressure
b) 2000 psig burst pressure and 800 psig working pressure
c) 4000 psig burst pressure and 400 psig working pressure
d) 4000 psig burst pressure and 800 psig working pressure

Answer 1

R-410A requires a gauge and hose set with a 4000 psig burst pressure and 800 psig working pressure to safely handle the refrigerant's high operating pressures.

Step-by-step explanation:

R-410A requires a high-pressure manifold gauge and hose set. The correct specification for the set they must have is a 4000 psig burst pressure and 800 psig working pressure.

It's essential when working with this refrigerant in air conditioning systems to use gauges and hoses capable of safely handling the pressure, as R-410A operates at significantly higher pressures than its predecessor R-22.
