Plastic Cap® is supplied with seal to keep the glass free from dust, dirt and grease|
Disassembly for installation is unnecessary with extended fittings on small size solder models|
Seals are easy-to braze|
Large full view sightglass, extra large crystal clear sightglass for viewing the refrigerant|
Bubbles indicate a shortage of refrigerant or a restriction in the liquid line|
Reversible indicator colors differ so widely between the wet and dry condition, there is no possibility of confusion|
Colors reverse as often as moisture concentration in the system changes
