Value Brand 4CFK8 Commercial Pressure Gauge 0 to 3,000 psi 3 1/2 in Dial 1/4

SKU CH-YJ1Q-VSV3H

Measures pressure up to 3000 psi with a 3 1/2 inch dial and 1/4 inch NPT connection

  • TypeElectronic
  • Measures up to 3,000 psi for demanding industrial tasks
  • +/-3-2-3% accuracy ensures reliable readings across the range
  • 304 stainless-steel case resists corrosion in harsh environments
  • 3-1/2 inch dial with white face provides clear visibility
  • 1/4 NPT male bottom connection fits standard piping

Pressure range and dial size

This commercial pressure gauge measures from 0 to 3,000 psi and features a 3 1/2 inch white dial for clear readings. It is built for technicians who need reliable pressure monitoring in industrial or automotive systems. The 1/4 inch NPT male bottom connection fits standard ports directly. Buyers who need a digital readout or a different pressure span should look elsewhere.

Case material and vibration resistance

The 304 stainless steel case resists corrosion in harsh environments while the liquid-filled design dampens needle vibration for stable readings. Acrylic lens protects the dial face from impact and contaminants. No external power is required so operation stays silent and there is no electrical draw. Users who need an IP-rated enclosure or a dry gauge will not find those features here.

Connection and calibration details

The gauge ships with a fixed 1/4 inch NPT male bottom mount and is not field fillable, so the fill fluid cannot be topped up on site. Accuracy follows a +/-3-2-3 percent specification across the scale. California Proposition 65 warnings apply due to listed chemicals. Installers who require a different thread type or a user-adjustable pointer must choose another model.

Questions about this item

How do I install the 1/4 in NPT male connection, and what is the common mistake?

Thread the 1/4 in NPT male fitting into the matching female port and tighten with a wrench on the 304 stainless steel case flats. The step people get wrong is turning the gauge by the 3 1/2 in dial or acrylic lens, which can damage the movement.

What maintenance or replacement will the Zoro Select 4CFK8 need over time?

The gauge is not field fillable and has no liquid dampening, so the primary maintenance is checking the +/-3-2-3 percent accuracy against a known standard. If calibration drifts beyond that tolerance, the entire unit must be replaced.

What limit appears first when the gauge runs continuously at high pressure?

Sustained operation near the 3,000 psi upper range will stress the dry, non-liquid-filled movement first, causing the +/-3-2-3 percent accuracy to degrade before the 304 stainless steel case or acrylic lens shows any wear.
