SKU CH-4DPQ-65Y23

Bronze water gauge with 16 in glass, 200 psig rating, 400 °F max temperature, and CRN 6616.5C registration

  • 200 psig max operating pressure for reliable system monitoring
  • 16 in gauge glass provides clear water-level visibility
  • 400 °F max media temperature suits high-heat applications
  • CRN OF 6616.5 registration confirms code compliance
  • Bronze body with EPDM gasket resists corrosion and leakage

Apollo 2020800 Bronze Water Gauge

The Apollo 2020800 is a bronze water gauge with a 16 in glass and 3/4 in MNPT connections. It suits plant engineers and maintenance crews who need direct liquid-level reading on vessels or piping. The needle-drain valve and two guard rods protect the glass during routine blow-down. Maximum operating pressure is 200 psig and media temperature reaches 400 Degrees F.

Replaces worn sight-glass assemblies

Swap this unit in when an existing gauge shows etched glass, leaking packing or corroded bronze body. The jump is worth it if the old hardware cannot hold 200 psig or the centre-to-centre dimension has shifted past 17 1/4 in. CRN registration OF 6616.5C confirms the design meets Canadian pressure-vessel requirements for regulated sites.

Straightforward NPT installation

Thread the 3/4 in MNPT ends into matching female ports using TFE tape or paste compatible with EPDM gaskets. Tighten evenly to avoid stressing the 16 in glass tube. Common issues are over-torquing the bronze body, which cracks the glass, and reusing old gaskets that fail at 400 Degrees F. Verify alignment before pressurising.

Questions about this item

What is the center-to-center length of the Apollo 2020800 water gauge for pipe alignment?

The center-to-center length is 17 1/4 inches, which determines the spacing needed between the upper and lower piping connections for proper mounting.

How do you install the needle drain valve on this gauge, and what step is often missed?

Thread the 3/4 inch MNPT connections into the piping using suitable sealant, then ensure the needle drain valve is fully closed before pressurising the system to 200 psig maximum.

When should the EPDM gaskets and TFE stem packing be replaced on this gauge?

Replace the EPDM gaskets and TFE stem packing if leakage appears at the glass or stem, or during routine maintenance when the gauge is exposed to temperatures near the 400 degree F maximum.
