Raptor Supplies is an authorised distributor of Oil Safe, Parker and Plast-O-Matic cooling sight glasses for indicating the moisture level in CFC, HCFC and HFC refrigerants. These units feature a wide-angle window for visual convenience and constant monitoring. Selected models are placed between a liquid-line filter dryer and a refrigerant control device to provide a leakproof viewing area. Their two-piece construction, with an O-ring, prevents pitting & etching of the glass body. Choose from a wide range of these sight glasses available in flare & sweat fittings.
