Description
Round tri-clamp sight glass in 1/4" thick polycarbonate, mounted between a pair of sanitary tri-clamp ferrules. It is offered in 1.5", 2" and 3" tri-clamp sizes, with the maximum working pressure falling as the bore diameter rises.
Maximum pressure by tri-clamp size
- 1.5" tri-clamp — 60 psi
- 2" tri-clamp — 55 psi
- 3" tri-clamp — 50 psi
The tri-clamp and the gasket are not included with the sight glass and are ordered separately.
These ratings are materially lower than the Meta sight glass in the same range, which is rated 200/150/100 psi across the same three sizes. Check both the working pressure and the chemical compatibility of polycarbonate against your process fluid before specifying this version.
