Value Brand

Value Brand Boiler Gauge 0-75 PSI 60-260 F Window

SKU CH-HW8Z-M22DP

Measures boiler pressure to 75 psi and temperature from 60 to 260 °F with a center-back 1/4 in MNPT connection

  • Product typeElectronic
  • Dual PSI and Fahrenheit scales simplify boiler monitoring
  • 0 to 75 PSI range suits typical hydronic systems
  • 60 to 260 F temperature span covers normal operating temps
  • +/-3-2-3 percent pressure accuracy ensures reliable readings
  • Brass wetted parts resist corrosion in hot water circuits

Boiler Gauge for Pressure and Temperature Monitoring

This round boiler gauge displays both pressure and temperature on a single dial. It is designed for technicians and facility managers who need to verify boiler operating conditions at a glance. The dual-scale face shows readings in psi and degrees Fahrenheit. A center-back connection allows direct mounting on compatible boiler fittings.

Steel Case with Brass Wetted Parts and Plastic Lens

The gauge case is constructed from black steel for durability in mechanical rooms. Wetted parts are brass and bronze, suited for water and steam service. A plastic lens protects the dial while keeping weight low. The 1/4 inch MNPT center-back thread fits standard boiler tappings without extra adapters.

Accuracy Specifications Define Suitability

Pressure accuracy follows a +/-3-2-3 percent grade across the 0 to 75 psi range. Temperature accuracy is rated at +/-3 percent across the 60 to 260 degrees Fahrenheit span. These tolerances determine whether the gauge meets the precision requirements of a specific inspection or control task.

Questions about this item

What does the +/-3-2-3 percent accuracy mean for the 0-75 psi pressure range?

The gauge reads within +/-3 percent of full scale on the first and last thirds of the dial and +/-2 percent on the middle third.

What size fitting and thread type does the 1/4 inch MNPT centre-back connection require?

It needs a female 1/4 inch NPT port on the boiler so the male taper thread can seal directly.

How do I install the gauge without cracking the plastic lens or stripping the brass socket?

Apply PTFE tape to the 1/4 inch MNPT threads, hand-tighten into the female port, then finish with a wrench on the brass socket flats only.
