The APOLLO VALVES CON-2025103 is a 1/2 inch water gauge designed for clockwise (CW) operation and supplied without glass. Water gauges of this type are used to provide visual or mechanical indication of water levels in boilers, tanks, and piping systems. This unit is installed by licensed plumbers and HVAC technicians in residential and light commercial applications where accurate water level monitoring is required. The 1/2 inch connection size makes it a standard fit for common boiler and tank configurations. The absence of a glass sight component indicates this gauge is intended for use with a separate or alternative level-reading assembly.
This water gauge is suited for installation on boilers, expansion tanks, water storage vessels, and similar plumbing or hydronic heating system components. It is appropriate for residential and light commercial settings where a 1/2 inch clockwise-threaded water gauge connection is specified. Installers should verify thread type and system pressure rating before installation to ensure proper fitment with the existing system.
Designed as an OEM-style replacement or new-installation water gauge for residential and light commercial boilers, tanks, and hydronic piping systems using a 1/2 inch clockwise-threaded gauge connection.
Installation should be performed by a licensed plumber or qualified HVAC technician. Shut off water supply and depressurize the system fully before removing or installing the gauge. Verify thread type and system pressure compatibility prior to installation. Follow all applicable local plumbing codes and manufacturer guidelines.
