Gauges and hoses

dilysi_3 · Apr 30, 2010

I have a quick question for you guys... I have a set of gauges that are for R12 R22 and R502 and the problem im having when i take the gauges off a system and put them away the gauges start rising. Is there something im doing wrong and is there any way to fix it

IMO, the residual gas in the hoses/manifold are responding to temp changes. you can open for the afternoon and let the pressure out.

Thats right the gas pressure will rise as the temp in your van rises . What you can do is before you take them off just take off the highside and open both valves (as long as you have low lostfittings) and let the comp. bring down the pressure in your hoses to running suction pressure.

Reverse the middle hose, leave it a little loose on the park and open the manifold valves.

Either that or deal with it.

Let those babies breath (its best to always vent the residuals)

Put them in the fridge to get the psi back down. :bsing:
