Saddle sight glasses are available for refrigerant lines from 7/8 to 4-1/8 inches, suitable for all commercial system applications, says the company. Requiring only a single brazing operation, the saddle is brazed directly to a drilled liquid line, then the appropriate sight glass is threaded into the saddle. A neoprene gasket between saddle and the sight glass body provides leaktight sealing. The sight glasses are offered with or without a moisture indicator. The sight glasses use hermetically sealed tempered crystal glass for maximum transparency and safety. Designed for a maximum working pressure (MWP) of 500 psig, the sight glasses can be used with media temperatures from -58° to 176°F. For volume users, the sight glasses are available in bulk packs.
