Luneta’s new Sight Glass has all the clarity and durability you need, with none of the leaks, cracks or squinting you may be used to with those old-style sight glasses. You’ll never have to use fragile, dark, hard-to-read sight glasses again. It comes in 8 English sizes from 0.25 to 2 inches and 10 metric sizes from M10x1.0 to M33x2.0.
