APOLLOVALVESABWCON2025103 ABW-CON-2025103 Water Gauge Glass

Product Description

The APOLLOVALVESABWCON2025103 ABW-CON-2025103 is a heavy composition water gauge glass set designed for boiler and hot water system water level monitoring. Built on the standard 20 Series platform, this unit features a heavier valve body pattern rated for higher service conditions. The set ships less glass rod, allowing the technician to install appropriately sized sight glass for the application. Fitted with an integrated auto ball valve, it provides automatic shutoff if the glass fails, reducing the risk of uncontrolled water release during service. The 1/2-inch pipe connection and 5/8-inch by 12-inch glass size make this a common fit for residential and light commercial boiler applications.

This water gauge assembly is suited for installation on boilers, hot water heaters, and pressurized water vessels where visual water level indication is required. The heavier valve body construction supports higher pressure and temperature service ratings compared to standard-duty gauge glass fittings. It is typically installed by licensed plumbers or HVAC technicians servicing hydronic heating systems. The auto ball valve feature is particularly valued in occupied buildings where rapid isolation of a broken sight glass is a safety priority.

Key Features

• Heavy valve body pattern rated for higher service pressures than standard 20 Series fittings
• Integrated auto ball valve provides automatic shutoff on glass failure
• Ships less glass rod, allowing field selection of appropriate sight glass length
• 1/2-inch pipe connection for standard boiler gauge glass fittings
• Aluminum and glass construction for corrosion resistance in wet service environments
• 5/8-inch by 12-inch gauge glass size suits residential and light commercial boilers

Compatibility

Designed as an OEM-style replacement or new-installation fitting for 1/2-inch pipe boiler and pressurized water vessel gauge glass connections requiring a heavy-body valve pattern with auto ball valve shutoff.

Installation Notes

Installation should be performed by a licensed plumber or qualified HVAC technician in accordance with local plumbing codes and the applicable sections of the International Plumbing Code (IPC). Shut off system pressure and allow the vessel to cool before removing any existing gauge glass hardware. Inspect all packing nuts and seals before placing the assembly into service. Never operate a gauge glass assembly with cracked, chipped, or improperly seated sight glass.
