Navac, Lyndhurst, New Jersey, releases its all-new NH5L left-handed thread hose. To differentiate newer, slightly flammable A2L refrigerants from A1 non-flammable ones, refrigerant tanks containing R-32 and R-454B have adopted left-handed connections. The new thread hose differs from traditional thread hoses by its orange colour and two rings on the reverse threaded side (versus one ring on a conventional thread).
