Bronze water gauge with 12-inch glass tube and two guard rods

Apollo

Apollo 2015100 Water Gauge 1/2 in MNPT Bronze

SKU CH-XJR3-PVK4A

Bronze water gauge with 12 in glass, 125 psig rating and 350 °F maximum temperature

  • Bronze body resists corrosion in water systems
  • 125 psig maximum pressure handles demanding industrial lines
  • 350 °F temperature rating suits hot water and steam
  • CRN registered OF 6616.5C meets Canadian safety standards
  • Two guard rods protect glass from impact damage

Apollo 2015100 Water Gauge for 1/2 in NPT Lines

The Apollo 2015100 water gauge fits 1/2 inch NPT connections and provides direct visual level monitoring for steam or hot water systems. Its bronze body and EPDM gaskets handle media temperatures up to 350 degrees F and pressures to 125 psig. CRN registration OF 6616.5C confirms compliance for Canadian installations.

Bronze body with 5/8 in glass and twin guard rods

The gauge glass measures 12 inches long with a 13 1/4 inch centre-to-centre spacing, giving a clear sight window between the two guard rods. Ball-check valves in the connections automatically shut off flow if the glass breaks, protecting personnel and equipment. TFE stem packing resists high-temperature steam without hardening or leaking.

Replaces damaged or unrated sight glasses

Upgrading to this unit adds the safety of automatic ball checks and a CRN-rated assembly where plain glass fittings were used before. The jump is worth it when operating near the 350 degree F or 125 psig limits, or when local code requires registered components. It does not suit applications needing larger pipe sizes or higher pressure ratings.

Questions about this item

What is the maximum operating pressure the Apollo 2015100 water gauge can handle continuously?

The gauge is rated for a maximum operating pressure of 125 psig, which is the limit reached first under sustained use.

How much heat can the bronze body and EPDM gaskets tolerate during all-day operation?

The unit handles media temperatures up to 350 degrees Fahrenheit, so the bronze body and EPDM gaskets remain within their rated thermal limits during continuous duty.

Which pipe fitting must already be in place to install this 1/2 inch NPT gauge?

A 1/2 inch female NPT threaded connection is required on the existing piping to accept the gauge's male NPT ends.
