Reducing nut for new refrigerants R32 and R1234yf. The 1/4 "SAE external thread allows connection of a hose for filling refrigeration systems with a cylinder containing a refrigerant equipped with a W 22.8 x 14 threaded connection. The nut is fitted with a perfectly matched, wear resistant gasket. Due to the different characteristics and safety requirements in cylinders on R32 and R11234yf, a left-hand thread was used to avoid mistakes.
