Commercial pressure gauge 0 to 100 psi

This general-purpose dial gauge measures system pressure from zero to 100 psi with a two-inch acrylic lens. The stainless-steel case and wetted parts suit industrial and automotive test applications.

Accuracy class and pressure headroom

The instrument reads within a plus or minus three-two-three percent accuracy envelope across the full scale. Readings remain reliable up to the 100 psi limit, beyond which the gauge cannot indicate pressure.

Center-back NPT connection and mounting

A quarter-inch male NPT thread on the centre back connects directly to compatible ports without extra fittings. The unit is not panel-mountable, so it installs in-line or on a test stand where front access is available.

Questions about this item

Will the 1/4 in NPT male center-back connection fit my existing 1/4 in NPT female ports?

Yes, the gauge has a 1/4 in NPT male process connection on the center back, so it threads directly into standard 1/4 in NPT female fittings.

How do I verify the +/-3-2-3 percent accuracy after installation?

Apply a known reference pressure and compare the 2 in dial reading; the pointer should stay within the stated +/-3-2-3 percent tolerance across the 0 to 100 psi range.

Does the box include any panel-mount hardware or sealant for the 1/4 in NPT threads?

The gauge is not panel-mountable and ships without mounting hardware or thread sealant; supply PTFE tape or pipe dope and any required brackets separately.
