Tube-style sight glasses mount to the outside of liquid storage containers. They use a glass tube to monitor and show levels within a container.

Tube-style sight glasses for expansion tanks monitor and show hot water levels in supply systems for commercial buildings and industrial facilities.

Tube-style sight glasses with check valves monitor and show fluid volume within a container. Their check valves shut off the liquid supply to the sight glass in the event of a break to prevent spills.

Hand pumps for hydraulic fluids with gauges are sealed to prevent hydraulic fluids from spilling out during use. They support pump operation in any orientation, such as horizontal, vertical, laid flat, or raised.

Gauge cocks help prevent rapid loss of fluid from accidental glass breakage. These valves are mounted on either side of the glass sight to isolate the chamber from liquid within the container. They are suitable for use with various fluids in heavy or lightweight industrial, municipal, petrochemical, and utility applications.
