EPA and NATE requirements
Is it within EPA and NATE requirements to allow refrigerant to spray from your hoses for a couple of seconds when you disconnect your gauge set from the service valves?
NATE does not regulate refrigerants.
Building Physics Rule #1: Hot flows to cold.
Building Physics Rule #2: Higher air pressure moves toward lower air pressure
Building Physics Rule #3: Higher moisture concentration moves toward lower moisture concentration.
A purging of the manifold hoses is permited, within reason.
When disconnecting your hoses some release would be di minimis release. It's been a while since the EPA cert test but I remember this being legal. It is still best to use low loss fittings.

Sorry had to add this.
4) Small releases of refrigerant that result from purging hoses or from connecting or disconnecting hoses
to charge or service appliances will not be considered violations of the prohibition on venting.
However, recovery and recycling equipment manufactured after November 15, 1993, must be
equipped with low-loss fittings.

replace your hoses, or buy low loss adapters.
heh, you looking to get a tech in trouble that came to your house?
