I bought it awesome at the price, but I am carefully building it. It is heavily heavy, golden part is brass and knurled is also firmly processed so it is easy to put power. The thinner one fits the rice tire valve. The air conditioning gas goes out gradually little by little over a year, but if it is not a valve loose it will come to a valve. .
Used to retighten the valve of the cooler compressor. It could be used for high pressure with a thick inner diameter, but for thin low pressure the remover was too thick to turn. Is the size different for 134a too?
