The SG+ Sight Glass Family
A clear view of flowing refrigerant, together with a humidity indicator lets you keep an eye on your system’s refrigerant. Lighter and more compact than traditional sight glasses, SG+ models have a wider viewing area and the finest indicator available, and are the industry’s only sight glasses formed from deep-drawn stainless steel. Available in a range of sizes from 1/4 to 7/8 in., in flare, sweat, and socket body styles. With a maximum working pressures up to 667 psig, the new SG+ family are suitable for today’s environmentally friendly high pressure refrigerants. Because they are stainless steel, they are little affected by brazing heat and operating ambient.
