SKU CH-Q7MS-JHP3Y

Commercial pressure gauge measures 0 to 3000 psi with a 304 stainless steel case and 1/4 NPT connection

  • Measures up to 3000 psi for high-pressure systems
  • 3 1/2 in dial provides clear, easy reading
  • 1/4 in NPT male connection fits standard fittings
  • 304 stainless steel case resists corrosion in tough environments
  • +/-3-2-3 percent accuracy delivers reliable pressure monitoring

Commercial Pressure Gauge 0-3000 psi

The Zoro Select 4FMY9 is a commercial pressure gauge built for pressure-washer systems and similar high-pressure water applications. It reads from zero to 3,000 psi on a 3 1/2 inch white dial with a silver 304 stainless steel case and acrylic lens. The gauge is designed for operators who need a direct, analog pressure indication during cleaning or maintenance tasks.

Center Back 1/4 NPT Mounting

A 1/4 inch male NPT connection on the center back lets the gauge thread straight into a pump outlet or accessory port without extra adapters. The 304 stainless steel case resists corrosion from water and cleaning chemicals, while the fixed acrylic lens protects the dial face. No liquid fill or vibration damping is included, so the needle will respond instantly but may flutter under strong pulsation.

Upgrade From Basic Analog Gauges

This unit replaces lower-range or plastic-cased gauges that cannot withstand 3,000 psi or prolonged outdoor exposure. The +/-3-2-3 percent accuracy class suits general commercial monitoring where precise calibration is not required. It is not for buyers who need a liquid-filled gauge for severe vibration, a field-fillable design for altitude adjustment, or an IP-rated enclosure for wash-down environments.

Questions about this item

What pressure range does the 0 to 3,000 psi gauge cover in practice?

The gauge measures from 0 to 3,000 psi with an accuracy of +/-3-2-3 percent across the dial.

What thread size and material are required to mount the 1/4 in NPT connection?

It needs a female 1/4 inch NPT port; the gauge stem is 304 stainless steel with a centre-back male thread.

How is the acrylic lens gauge installed, and what step is often missed?

Thread the 1/4 NPT male stem into a female port using PTFE tape on the threads; the common mistake is omitting the tape and causing leaks.
