What this gauge measures

This commercial pressure gauge reads from 0 to 100 psi on a 2 1/2 inch dial. It is built for technicians who need a direct-reading instrument on compressed-air, hydraulic or water lines. The 1/4 inch male NPT connection threads into standard ports without adapters.

Sustained-use behaviour

The case and wetted parts are 304 and 316 stainless steel, so the gauge resists corrosion during continuous service. Accuracy follows a +/-3-2-3 percent pattern across the scale, meaning the middle range stays tighter than the ends. The acrylic lens and unrated IP classification mean the dial stays legible but the unit is not sealed against wash-down or immersion.

Check before ordering

Verify that your process connection is 1/4 inch female NPT and that the pressure range never exceeds 100 psi. Confirm the mounting location can accept a bottom-entry, non-panel-mountable gauge. Note the Proposition 65 warning: the product contains a chemical known to the State of California to cause cancer and reproductive harm.

Questions about this item

Does the 2 1/2 in dial stay legible when the gauge is running continuously on a hot water line?

The acrylic lens and 304 stainless steel case resist heat distortion, so the 0-100 psi scale remains readable during all-day operation.

What thread sealant or adapter do I need to connect the 1/4 in NPT male fitting to my existing pipe?

The 1/4 in NPT male bottom connection threads directly into a matching female NPT port; apply PTFE tape or pipe dope for a leak-free seal.

Will the 316 stainless steel sensor survive contact with the older brass fittings in my system without corrosion?

316 stainless steel resists galvanic corrosion better than many alloys, so it pairs reliably with legacy brass components in typical water or air lines.
