    410a refrigerant burns


    guy's

    has anyone else noticed that 410a seems to burn far more than any other refrigerant?

    almost every time i remove my gauge lead i end up with a burnt finger(s). I know I'm not doing anything different to 22 or 407c etc so it must be the gas...

    cheers

    I've not had the pleasure of being burnt by it yet
    This may be too simple but do you think it could be because it is so cold compared to R22 at ambient. Its about 20degc lower.

    or maybe that it is a million psi higher than r22 so you have a million psi more in your guage line!or maybe you didnt follow the instruction that b&q gave you when you bought the unit.sorry i`m having a bad day.

    I trust that you are using protective gloves and shut off valves on your gauge lines there Richard

    They're starting to take it as a challenge...

    BASIC MAINTENANCE. If it doesn't move and it should then use WD40. If it moves but it shouldn't then use Duct Tape.

    Valves on 410 gages are good and we all know we should always wear gloves

    Yeah, I had a nasty nip from R410 this Summer. Because of the higher pressure it is more difficult to unscrew my connectors and allows more refrigerant to escape, in this case getting cold enough to freeze the skin even in my gloves, because my gloved are quite short, liquid refrigerant managed to get around my watch strap and make a real mess of my wrist. I have bought a couple of quick connectors for R410 from RPW but they will only connect to 1/4 inch flair hoses

    Get the quick coupler set from SRW, I've had them for 2 years now, never had a cold burn since
