IMT 1/8 NPT fuel pressure gauge adopts high-precision Bourdon tube design and airtight vibration-resistant structure to ensure accurate readings under severe vibration environment. As the source factory of deep-cultivated instrument manufacturing, Hangzhou East Asia Instrument (IMT) has more than 10 professional production lines, supporting OEM customization and direct supply in large quantities, ensuring that you can obtain extremely advantageous unit price and fast production cycle.

Mainly used in high-performance racing fuel systems, industrial generator sets, hydraulic power units and various types of pneumatic machinery pressure monitoring.

strictly follow the US pipe thread standard, and the tolerance is controlled within 0.01mm to ensure perfect adaptation to the fuel regulator or track and eliminate hidden dangers of leakage during installation.

the case adopts fully sealed welding process and is filled with damping liquid, which can absorb mechanical vibration within 200Hz frequency, make the pointer stable and not shake, and extend the service life by 50%.

The pressure-sensitive components that contact the fuel are made of 316L stainless steel, which effectively resists the erosion of chemical additives in the fuel and prevents precision drift after long-term use.

thickened impact-resistant window material is used, which does not burst under extreme pressure impact, and does not yellow after long-term contact with oil stains, ensuring clear readings for maintenance personnel at any time.

the dial scale is printed with high resolution, and the double unit (PSI/Bar) contrast is clear, which can realize fast and accurate numerical interpretation even in low light environment.

with 1.3 times the range of instantaneous overload protection capability, to prevent the fuel pump starting instantaneous pressure pulse damage instrument internal movement.

IMT 1/8 NPT fuel pressure gauge far exceeds the industry standard in material selection. We insist on using a stainless steel shell with a thickness of 0.5mm, combined with a thickened Bourdon tube. Compared with similar products, the zero return error of IMT instrument remains within 0.5% after 100000 pressure cycle tests, which greatly reduces the frequency of late replacement.




Provides accurate monitoring of high-performance fuel injection systems, helping engineers adjust fuel delivery curves based on real-time pressure feedback.

suitable for fuel supply pipeline, integrated on the equipment panel as a standard supporting component to ensure long-term stable operation of the engine.

For wholesalers looking for high-quality, US-standard interface meters, IMT offers OEM brand customization and competitive bulk prices.

suitable for all kinds of pressure testing equipment requiring 1/8 NPT interface in the factory, providing reliable on-site pressure verification tools.


Please wind an appropriate amount of raw material tape on the 1/8 NPT thread before installation to ensure the air tightness of the connection with the system.

Use a wrench to fix the hexagon of the instrument connector for installation. Do not directly grasp the watch case for rotation to prevent deformation of the watch case.

After installation, please cut or dial the tip of the sealing plug on the top of the case to the open position to balance the atmospheric pressure and ensure accurate readings.

Please ensure that the normal operating pressure of the system is between 1/3 and 2/3 of the full scale of the meter to obtain the best measurement accuracy.
