WATER PRESSURE METER 1/8 Inch(3.175 mm)

To check the pressure of water/Gas

Brass material -Imported

With 1/8 inch male threaded inlet

Pressure meters (pressure gauges) with 1/8-inch threads

are very common in low- to medium-pressure, compact, and

instrumentation applications where space is limited

Common Devices Using 1/8-Inch Pressure Gauge Threads

Common Devices Using 1/8-Inch Pressure Gauge Threads

1. Water & Plumbing Applications

Drip irrigation systems / RO (Reverse Osmosis) water purifiers

Water pumps (booster, domestic, garden pumps) / Inline pressure regulators

Filter housings (screen filters, sediment filters) 

 Common in home gardens, hydroponics, and light commercial plumbing

 2. Pneumatic & Air Systems

Air compressors (small/portable types) / Air regulators (FRL units)

Pneumatic control panels / Air tools (sprayers, nail guns, inflators)

Widely used in workshops and small industries

3. Gas & Fuel Systems (Low Pressure)

LPG regulators (low-pressure side)

Natural gas test points / Biogas lines

Must use gauges specifically rated for gas

4. Hydraulic & Mechanical Equipment (Light Duty)

Small hydraulic power packs / Testing ports in hydraulic circuits

Grease pumps and lubrication systems

 5. Instrumentation & Process Control

Laboratory equipment / Pressure testing rigs

Calibration benches / Medical and dental equipment

Chemical dosing systems 

6. Agriculture & Irrigation

Fertigation units /Mist / fogging systems

Sprinkler lines / Pressure controllers in greenhouses

Thread Standards Commonly Seen in 1/8-Inch Gauges

Make sure the thread type matches your fitting:

1/8" BSP (BSPT / BSPP) – very common in India

1/8" NPT – common in imported gauges

1/8" Metric adapters (used with reducers)

 Always verify thread type, not just size.

 Typical Pressure Ranges for 1/8-Inch Gauges

0–1 bar / 0–2 bar / 0–4 bar / 0–10 bar

Vacuum / compound gauges
