Value Brand Altitude Pressure Gauge 0-370 psi 4 1/2 in 1/4 in NPT 18C812

SKU CH-5MKZ-DK698

Measures altitude pressure from 0 to 370 psi with a 4 1/2 in stainless steel dial and 1/4 in NPT bottom connection

  • TypeElectronic
  • Accurate altitude readings with ±1.0 % precision
  • Wide 0-370 psi range suits many pressure tasks
  • Stainless-steel case resists corrosion in tough environments
  • Acrylic lens protects dial from impact and scratches
  • Copper sensor and socket ensure reliable signal transfer

Pressure Gauge 0-370 psi

The Value Brand altitude pressure gauge measures from 0 to 370 psi with a 4 1/2 inch dial and a 1/4 inch NPT male bottom connection. It delivers an accuracy of +/- 1.0 percent across a process temperature range of -40 to 140 degrees Fahrenheit. The stainless steel case and acrylic lens protect the copper sensor and socket.

Suited For And Not Suited For

This gauge suits technicians monitoring altitude-related pressure in hydraulic or pneumatic systems using a 1/4 inch NPT port. It is not for applications requiring panel mounting, an IP or NEMA rating, or a hazardous-location rating. Buyers needing a different pressure range or connection size should look at other models.

Key Specification Deciding Fit

The single specification that decides fit is the 0 to 370 psi range combined with the 1/4 inch NPT male bottom connection. If your system operates outside this pressure span or uses a different thread, this gauge will not install or read correctly.

Questions about this item

How do I install the 1/4 in NPT bottom connection and what step is often missed?

Apply thread sealant to the male NPT threads, then tighten into the female port using a wrench on the copper socket — not the case — to avoid stripping the soft copper fitting.

What maintenance will the copper sensor and socket need over time?

Inspect the copper sensor and socket periodically for corrosion or mineral deposits; clean gently if buildup appears and replace the gauge if the sensing element shows pitting or deformation.

What limit appears first during sustained use at high pressure?

The +/- 1.0 percent accuracy spec is the first limit reached under sustained pressure cycling; prolonged exposure near 370 psi can cause gradual drift beyond this tolerance.
