Commercial vacuum gauge for HVAC and refrigeration

This Value Brand 304 stainless steel vacuum gauge measures pressure from 30 to 0 inches of mercury. The 2 inch dial uses an acrylic lens and a white face for clear reading. A 1/4 inch male NPT bottom connection fits standard service ports. The gauge is liquid-filled for vibration resistance and carries a +/-3-2-3 percent accuracy rating. It is intended for technicians who need a durable, field-serviceable instrument.

Replaces worn analogue gauges when calibration

Upgrade when an existing gauge shows erratic needle movement or loses zero after repeated evacuation cycles. The liquid-filled case dampens pulsation that can damage dry movements. The 304 stainless steel case resists corrosion from refrigerant oils and moisture. The jump is worth it if the current gauge lacks a bottom-mount NPT fitting or if the lens is cracked and fogged.

Accuracy class limits precision on deep evacuation

The +/-3-2-3 percent tolerance means the reading can deviate more at the low end of the scale. The gauge is not IP or NEMA rated, so it should not be exposed to wash-down or outdoor weather. Acrylic lens can scratch if wiped with abrasive cloths. The instrument is not field-fillable, so a leaking fill fluid requires full replacement. California Proposition 65 warnings apply to materials in the product.

Questions about this item

What thread size does the 1/4 in NPT male connection require?

The gauge uses a 1/4 in NPT male process connection, so it threads directly into a matching 1/4 in NPT female port without adapters.

How should the gauge be oriented during installation to avoid reading errors?

With the process connection at the bottom, mount the gauge upright so the 2 in dial faces the operator; tilting it can trap air and shift the needle.

Can the liquid-filled damping fluid be topped up or replaced in the field?

The case is not field fillable, so the internal liquid fill is sealed for life and cannot be replenished by the user.
