For R-410A gauge sets, is the statement 'burst pressure 4000 psig and working pressure 800 psig' true?

Understanding how gauge sets are rated helps explain why this statement is true. Gauge sets have a working pressure—the maximum pressure they’re designed to handle during normal use—and a burst pressure—the pressure at which they would fail or rupture. For R-410A service, the high-side pressures can run quite high (typically well under 1000 psi and often around 450–550 psi in normal operation), while the low side is much lower. To ensure safety and accommodate pressure spikes, tools are built with a substantial margin between normal operating pressure and failure. A common specification for R-410A gauge sets is a working pressure of about 800 psi, with a burst pressure around 4000 psi. That large gap provides the necessary safety factor, so the statement reflects standard ratings.
