1/8 NPT Pressure Gauges

These gauges feature a 1/8 NPT (National Pipe Thread) connection, a compact thread size ideal for applications where panel or process space is limited. The one-piece case-to-socket design ensures a durable, leak-resistant seal at this connection point even under demanding industrial conditions.

Yes, these pressure gauges are compatible with diaphragm seals, which isolate the gauge's internal mechanism from corrosive, viscous, or particulate-laden process media. This extends instrument life significantly and is especially valuable in oil and gas applications involving aggressive fluids or slurries.

These gauges are widely used in upstream exploration and drilling, midstream pipeline transport, and downstream refining and processing within the oil and gas sector. They're also applied in general industrial process monitoring where compact, durable pressure instrumentation is required.

Yes, the heavy-duty one-piece case-to-socket construction is specifically engineered to withstand the rigors of upstream, midstream, and downstream oil and gas operations, including high-pressure and high-vibration environments. Optional accessories like needle valves further protect the gauge during pressure spikes.

Compatible accessories include needle valves for isolation and pressure surge protection, diaphragm seals for media isolation, and thermowells for simultaneous temperature monitoring. These accessories help extend gauge life and adapt the instrument to specific process conditions.

Selection depends on factors such as process pressure range, media compatibility, connection size, and environmental conditions like vibration or temperature extremes. Our team can help match the correct gauge and accessory configuration, including diaphragm seals or thermowells, to your specific operational requirements.
