High-Visibility Sights
Easily view liquid movement and level changes from a distance—these sights have an indicator ball inside the glass window. They also have a reflector that makes dark liquid easy to see, especially in low-light conditions.
UN/UNF (SAE Straight) threads are also known as O-ring boss threads; a gasket can be added to prevent leaks.
