63mm Pressure Gauges

63mm pressure gauges provide compact local pressure indication for industrial equipment, plant rooms, control panels and machinery where space is limited. This dial size is commonly used on pumps, compressors, hydraulic power packs, HVAC systems and general process instrumentation for routine pressure measurement and monitoring.

GNW Instrumentation supplies 63mm industrial pressure gauges for replacement, maintenance stock, OEM equipment and new installations. When selecting a gauge, match the pressure range, connection, mounting style and case type to the application and operating conditions.

Choosing a 63 mm Pressure Gauge

63 mm pressure gauges provide local indication for machinery, plant and process equipment. This widely used format balances compact installation with useful local readability on machinery, pumps and plant.

Choose the range around the normal operating pressure, then confirm the scale units, connection size, thread form and bottom- or back-entry arrangement. Mechanical gauges in this size are specified at ±1.6% FS; check the individual product for its complete specification.

Compare general-purpose, glycerine-filled, industrial and all stainless steel gauges according to the operating conditions and required materials.

Browse pressure gauge accessories for adaptors, mounting components, valves and protection options, or return to all pressure gauges.

63 mm Gauge Selection

63 mm describes the nominal dial diameter, not the pressure range or connection. This widely used format balances compact installation with useful local readability on machinery, pumps and plant.

When replacing an instrument, record the full scale, units, thread form, connection size and entry position. Matching the dial diameter alone is not enough.

Mechanical gauges in this size are specified at ±1.6% FS. Because this is based on full scale, consider the resulting allowance at the readings you need to monitor.

63 mm Dial

This widely used format balances compact installation with useful local readability on machinery, pumps and plant.

±1.6% FS Accuracy

The accuracy allowance is based on the complete measuring span rather than the current reading.

Typical Applications

Suitable for local pressure indication, maintenance replacement and equipment builds where a 63 mm dial and the selected specification suit the duty.

Hydraulic Systems

Used on hydraulic power packs, test rigs and machinery to monitor line pressure, system adjustment and routine operating conditions.

HVAC Plant

Suitable for pressure indication on heating, ventilation and building services equipment where compact gauge visibility is required.

Pumps and Compressors

Applied to pump sets, compressor packages and associated pipework for local pressure checks during operation and maintenance.

OEM Equipment Builds

A practical dial size for machine builders and equipment manufacturers requiring compact industrial pressure measurement components.

How to Choose

Select the pressure range, choose the required construction, match the connection and confirm that the dial will fit and remain readable.

Pressure Range

Match the gauge range to the normal working pressure of the system, allowing suitable headroom for safe and readable indication.

Connection and Mounting

Check the process connection size, thread type, entry position and whether the gauge is mounted directly, on a panel or with accessories.

Dry or Glycerine Filled

Use a dry gauge for stable pressure conditions and consider a glycerine-filled gauge where vibration, pulsation or pointer flutter is expected.

Media and Environment

Confirm compatibility with the process media, ambient conditions and any exposure to moisture, vibration or mechanical damage.

63mm Gauge FAQs

Common buyer questions when selecting or replacing compact industrial pressure gauges.

What is a 63mm pressure gauge used for?

A 63mm pressure gauge is used for local pressure indication on compact equipment such as hydraulic systems, HVAC plant, pumps, compressors and control panels.

Can I replace a larger or smaller gauge with a 63mm gauge?

Only if the pressure range, connection, mounting arrangement, readability and service conditions remain suitable. Always compare the existing gauge details before replacing.

When should I choose a glycerine-filled 63mm gauge?

A glycerine-filled gauge is useful where vibration or pressure pulsation causes pointer movement. The fill helps damp the movement for easier reading.

What should I check before ordering a replacement gauge?

Check the dial size, pressure range, thread, connection position, mounting type, dry or filled case requirement and compatibility with the media and environment.
