303 Stainless Steel Window Flow Sights are primarily used in low pressure oil lines. The air-tight glass sight allows visual observation of the liquid flow, clarity, and condition. There are no restrictions on the inside of the sight, resulting in the full flow of liquid, equal to the respective pipe size. The unit can be installed in any position (horizontally, vertically, or at an angle).
