Bronze water gauge with glass tube and two guard rods

Apollo

Apollo 2015000 Water Gauge 1/2 in MNPT Bronze

SKU CH-WN97-TRGTF

Bronze water gauge monitors liquid levels up to 350 °F and 125 psig with a 12 in glass and two guard rods

  • Bronze body resists corrosion in hot water systems
  • 125 psig maximum pressure handles demanding industrial applications
  • 350 °F temperature rating suits high-temperature media
  • CRN registered OF 6616.5C meets Canadian safety standards
  • Two guard rods protect the 12 in gauge glass from damage

Product Identity

The Apollo 2015000 is a bronze water gauge designed for industrial plumbing systems. It suits engineers and maintenance teams who need reliable liquid-level visibility on 1/2 inch NPT piping. The CRN registration confirms compliance with Canadian pressure-vessel standards. Buyers who require a different pipe size or a non-metallic body should look elsewhere.

Decisive Specification

The gauge glass measures 5/8 inch in diameter and 12 inches long with a 13 1/4 inch center-to-center length. This single dimension determines whether the unit fits the existing vessel tappings. The maximum operating pressure is 125 psig and the media temperature must not exceed 350 degrees Fahrenheit. If the application demands higher pressure or temperature ratings this gauge will not meet the requirement.

Installation Notes

The gauge connects via 1/2 inch male NPT threads and includes two guard rods for glass protection. Ball-check valves and TFE stem packing help prevent leakage during service. EPDM gaskets seal the glass ends but must be inspected for chemical compatibility with the process fluid. Over-tightening the packing nuts can damage the TFE material and cause weeping.

Questions about this item

What does the 125 psig maximum operating pressure mean when the gauge is installed in a live water line?

It sets the highest continuous pressure the bronze body, EPDM gaskets and TFE stem packing can handle without leaking or deforming, so the supply must stay at or below 125 psig.

How does the NPT connection type limit the way I pipe this gauge into a 1/2 in line?

The male NPT threads seal by taper engagement, so you must use a compatible female NPT fitting and thread sealant; other thread forms such as BSPT will not seal.

What physical space do the 12 in gauge glass and 13 1/4 in center-to-center length require for mounting?

You need at least 13 1/4 in of clear vertical run between the two NPT connections plus enough clearance around the 5/8 in glass and two guard rods for visual reading and maintenance access.
