R-410A requires a high-pressure manifold gauge and hose set. They must have a burst pressure and working pressure of which values?

R-410A service equipment must be built with a large safety margin between how it normally operates and the pressure it could fail at. The burst pressure shows the point at which the hose or gauge set would fail catastrophically, while the working pressure is the pressure it is designed to withstand during everyday use. For R-410A, the safety standard is a burst rating of about 4000 psi and a working pressure of about 800 psi. This five-to-one margin keeps the equipment safe even with pressure spikes that can occur in real-world service. The option with a burst of 4000 psi and a working pressure of 800 psi matches these specified safety ratings exactly, making it the best choice. The other options fall short on either the burst rating or the working pressure, which would not meet the required safety standards for R-410A.
