Note: I-012 is my inventory # only. Here is a BRAND NEW Reotemp PT45P1A2P23-G-P Process Pressure Gauge. This one has a range of 0-600 PSI. 4.5″ Gauge, 316SS tube and socket, 1/2″ NPT lower mount. These have a 316L flange on them with a bottom 1/2 NPT port.. Sticker on back of gauge says model: W51722SSS-SGDTD-BH-GS. Note: These are BRAND NEW MRO spares in their original box. The box may or may not have writing on it, some oil spots on the outside from being stored with other gauges, etc… But product is BRAND NEW.
