|LEVEL EYE� SIGHT GLASSES|
The Level Eye� is a reliable, industrial type sight glass. The unique reflex lens indicates the true level of liquid present without requiring a second lens. The lens appears dark in the presence of liquid and clear when liquid is not present.
The standard length frost shield allows clear vision with refrigerant temperatures down to -20F, and a 1 " longer frost shield is available for refrigerant temperatures below -20F.
Level Eyes are available with clear or reflex lenses, with square or saddle milled ends, in carbon steel and stainless steel, in both welded and threaded housings.
