Commercial Pressure Gauge 0-600 psi

The Zoro Select 4CFN1 is a commercial pressure gauge built for pressure-washer systems that operate up to 600 psi. Its 1 1/2 inch dial and 1/8 inch NPT male connection suit installers and maintenance crews who need a direct-reading instrument on pumps, hoses or accessory ports. The gauge is supplied new and carries California Proposition 65 warnings for cancer and reproductive-harm substances.

Center-back mount and vibration resistance

A center-back process connection lets the gauge sit flush against a panel or bracket, saving space in tight equipment layouts. The liquid-filled case dampens needle flutter caused by pump pulsation, so readings remain steady while the washer runs. No field-fill option is provided; the unit arrives sealed and ready to install.

304 stainless case with acrylic lens

The case is made from 304 stainless steel with a silver finish, and the dial is white for high contrast against the black scale. An acrylic lens protects the face from splashes and debris common in outdoor cleaning environments. The gauge carries no IP or NEMA rating, so it should be mounted where direct, sustained water jets cannot reach the lens or connection.

Questions about this item

How often will the 1/8 in NPT connection need resealing or replacement?

The 1/8 in NPT male thread is a standard tapered pipe fitting; resealing is only required if the thread sealant degrades or the connection is loosened during service.

What is the first limit reached when the gauge operates continuously at 600 psi?

The gauge is rated to 600 psi primary pressure range with +/-3-2-3 percent accuracy; sustained operation at the top of the range keeps the Bourdon tube at its maximum elastic deflection.

How much heat does the 304 stainless steel case generate when the gauge runs all day?

The dry, non-liquid-filled gauge produces no measurable self-heating; the 304 stainless steel case simply tracks the temperature of the process fluid and ambient air.
