Zoro Select 4FLV9 Commercial Pressure Gauge 0 to 100 psi 2 1/2 in Dial 1/4 in NPT

Commercial Pressure Gauge 0 to 100 psi

This commercial pressure gauge measures from 0 to 100 psi with a 2 1/2 in dial. It is built for pressure washer systems and similar equipment where operators need a clear, direct reading of pump or line pressure. The bronze sensor and brass socket suit typical water-based cleaning applications.

1/4 in NPT bottom connection limits

The gauge installs via a 1/4 in male NPT thread at the bottom of the case. This single orientation and thread size restrict mounting to ports that match exactly; panels or alternative connection types cannot be used. The ABS plastic case and acrylic lens are not rated for hazardous locations or ingress protection.

+/-3-2-3 percent accuracy class

Accuracy follows a +/-3-2-3 percent grade across the scale, meaning the middle range reads tighter than the extremes. Buyers who need a tighter tolerance across the full 0 to 100 psi span should verify this grade meets their calibration requirements before purchase.
