What this gauge measures

This ZORO SELECT pressure gauge reads from 0 to 30 psi on a 1 1/2 in dial. It is built for technicians who need a direct-mount instrument on compressed-air or fluid lines. The 304 stainless-steel case and acrylic lens resist corrosion in workshop environments.

Check your connection before ordering

The process connection is a 1/8 in male NPT thread located at the centre back of the case. Verify that the port on your equipment matches this thread size and orientation. The gauge is not field-fillable and carries no IP or NEMA rating, so it must be installed where it will not be submerged or exposed to pressurised wash-down.

What the dry, vibration-resistant design changes

Because the gauge is supplied dry with no liquid dampening, the pointer responds quickly to pressure changes but will flutter more under pulsating flow. The vibration-resistant construction helps maintain the stated +/-3-2-3 percent accuracy in high-vibration settings such as compressor manifolds or pneumatic tool stations.

Questions about this item

What comes in the box with the Value Brand 4CFL3 pressure gauge, and what extra items do I need to buy?

The gauge is supplied as a single unit with a 1 1/2 in dial, 1/8 in NPT male centre-back connection, 304 stainless-steel case, acrylic lens and white dial. No fittings, tubing or sealant are included, so purchase compatible 1/8 in NPT adapters or pipe tape separately.

The gauge is listed as 0 to 30 psi with +/-3-2-3 % accuracy — which version or capacity should I choose for my application?

Only the 0 to 30 psi range is offered for this model. Select it when your system pressure stays within that span; the +/-3-2-3 % accuracy grade means the middle third of the scale reads within ±2 % and the outer thirds within ±3 %.

What does the 0 to 30 psi headline figure mean once the gauge is installed on a real machine?

It indicates the gauge will display pressures from zero up to 30 psi. Readings in the centre third of the dial are accurate to ±2 % of full scale, while the lower and upper thirds are accurate to ±3 %. The gauge is dry, not liquid-filled, and has no IP or NEMA rating.
