Zoro Select 4FMC4 Commercial Pressure Gauge

The Zoro Select 4FMC4 is a commercial pressure gauge designed for measuring pressure in industrial and commercial systems. It features a 2 in dial with an acrylic lens and a measurement range of 0 to 30 psi. The gauge uses a bronze sensor and brass socket for durability.

Verify Connection And Mounting Requirements

Before ordering confirm that your system uses a 1/4 in male NPT process connection at a center back location. The gauge is not panel mountable and carries no IP or NEMA rating so it must be installed in a protected environment. Check that the brass socket and bronze sensor materials are compatible with your process media.

Accuracy Profile Under Continuous Use

The gauge delivers an accuracy of +/-3-2-3 percent across its scale during sustained operation. The ABS plastic case and acrylic lens resist typical commercial wear but are not rated for hazardous locations. California Proposition 65 warnings apply as the product contains chemicals known to cause cancer and birth defects or reproductive harm.

Questions about this item

Does the gauge arrive ready to install, or do I need a separate fitting?

The gauge has a 1/4 in male NPT centre-back connection so it threads directly into a matching female port; no extra adapter is required.

Which accuracy grade should I pick for general workshop use?

The single model supplied carries a 3-2-3 percent accuracy specification, meaning the middle third of the scale reads within 2 percent and the outer thirds within 3 percent.

How will the 30 psi upper limit behave on a live air line?

The pointer will show pressure up to 30 psi; beyond that the needle pegs at the stop and the gauge no longer indicates the actual pressure.
