GAR sight glasses are constructed from a single forged brass block with riveted window to make it completely watertight. SPU models are fitted with a colour toner that is very sensitive to humidity, acid resistant and compatible with all refrigerant fluids. These features ensure strict, immediate control of the degree of humidity and the fluidity of the refrigerant fluid as a result of the variation in the colour of the paper (yellow = wet / green = dry). The SPL model can be used as a gauge of the pas sage of liquid and oil, and no colour toner means a wider area can be seen through the window. The ORS model has been designed to be fitted in the automotive field. A teflon gasket is suggested. The sight glasses are available in the flare version, soldering or ORS for automotive field. The entire line has been designed for use with almost all of the refrigerants present on the market, i.e. fluids classified in Arti cle 13, paragraph 1, letter (b), of Directive PED 2014/68/ EU as part of Group 1 and Group 2; most of these fluids are indicated in Annex E of standard EN 378-1 as Class A1, A2L and A3
