  • Copper alloy internals suit non-corrosive fluids

Industrial Pressure Gauge

The Zoro Select 18C767 is a mechanical pressure gauge built for industrial monitoring of non-explosive gas or liquid media. Its copper alloy sensor and socket resist corrosion from compatible fluids that do not crystallize. The 4-1/2 inch dial with tempered glass lens provides clear readings in demanding environments. It suits technicians who need reliable local indication without electronic signal output.

Accuracy and Construction

The gauge delivers an accuracy of +/- 1.0 percent of full scale across its operating range. A black nylon case protects the internal bourdon tube mechanism from ambient knocks and vibration. No IP or NEMA rating is assigned, so the unit is intended for sheltered installations away from wash-down or hazardous locations. The bottom-mounted male NPT connection allows direct in-line plumbing.

Quarter-Inch NPT Bottom Connection

Process attachment is a 1/4 inch male NPT thread located at the bottom of the case, limiting orientation to vertical piping. Media must be non-explosive and non-crystallizing to avoid damage to the copper alloy wetted parts. The gauge carries a California Proposition 65 warning for chemicals known to cause cancer and reproductive harm. Buyers needing panel mounting, flange connections or digital output must select a different model.

Questions about this item

How do I install this 1/4 in NPT bottom-mount gauge without stripping the copper-alloy socket?

Wrap PTFE tape on the male threads, thread by hand until snug, then tighten one half turn with a wrench on the socket flats — never turn the nylon case.

What part will need replacement first if the process media starts to crystallise?

The copper-alloy sensor and socket will corrode and must be swapped out before accuracy drifts beyond the 1.0 percent spec.

At what point does the 1.0 percent accuracy limit show up during continuous pressure cycling?

Accuracy holds within 1.0 percent until the copper-alloy sensor fatigues or the tempered-glass lens develops micro-cracks from repeated shock.
