A pressure gauge looks simple, but choosing the wrong one leads to poor readability, leaks or a unit that does not survive your process. WIKA is the world’s leading pressure-gauge manufacturer, and Twin Hydraulics Engineering supplies the full range in Malaysia. This guide walks through the three things that matter most when selecting a WIKA gauge: dial size, process connection and pressure range.
1. Dial size (how easy it is to read)
Dial size, given as a nominal size (NS) in millimetres, decides how far away the gauge can be read and how much room it needs. Common choices are NS40 and NS50 for compact panel mounting, NS63 for general machinery, and NS100 or NS160 where the gauge must be read from a distance. Browse gauges by dial size to narrow down quickly.
2. Process connection (how it mounts and seals)
The connection must match your port thread and orientation. WIKA gauges are available with 1/4" and 1/2" NPT, BSP/G and metric threads, in bottom (lower) or back (centre/lower back) mounting. Getting the thread and position right avoids adaptors and leak paths. See the options grouped by process connection.
3. Pressure range (accuracy and safety)
As a rule of thumb, choose a range so your normal working pressure sits in the middle third of the scale — roughly 25–75% of full scale. This protects the movement from over-pressure and keeps readings accurate. We list gauges from vacuum and compound ranges up to over 400 bar; filter by pressure range to find yours.
Liquid-filled or dry?
If your gauge will see vibration or pulsation — common on pumps and hydraulic power units — a liquid-filled gauge (such as the WIKA 213.53) dampens the pointer and extends service life. For clean, stable processes a dry gauge is fine.
