Diesel Pressure Gauge produced by Hangzhou East Asia Instruments is specially designed for high vibration diesel engine systems. Through hydraulic damping and 316L stainless steel core components, it ensures accurate readings of +/-1.6% under extreme pressure pulsation. We are a source manufacturing plant with more than 30 years of experience. We strictly implement ISO quality management, eliminate middlemen, and provide highly competitive ex-factory prices and customized services for global B2B buyers.

Diesel Pressure Gauge, mainly used in diesel generator sets, marine power systems, heavy construction machinery and industrial fuel transfer pumps.

the instrument is filled with 99% high-purity glycerin, which can effectively absorb the high-frequency vibration and pulsation generated by the diesel pump. This makes the pointer stable under extreme conditions, improves the reading stability by 85%, and significantly reduces the wear of the internal mechanical gears.

according to the chemical characteristics of diesel oil and additives, the contact medium part adopts 316L stainless steel Baughton tube. Compared with ordinary brass material, its antioxidant capacity is enhanced by 3 times, completely avoiding the risk of instrument leakage caused by fuel corrosion.

PSI and Bar dual-unit scale design to meet international engineering standards. High contrast aluminum dial combined with anti fog tempered glass mirror, even in the dark and narrow room environment can be clear at a glance, to prevent human reading error.

The structural design supports up to 130% instantaneous overload protection, and is equipped with a back safety pressure relief plug. When abnormal high pressure occurs in the system, the pressure will be released from the rear to effectively protect the operator and the front glass from being broken.

The shell adopts a seamless welding process, and the working temperature covers -20°C to 70°C. Whether it is an outdoor generator set in a severe cold area or a ship’s engine room with high temperature and humidity, the instrument can keep sealed and non-oil leakage, and the performance is stable for a long time.

Uniform precision ground 1/8 inch or 1/4 inch NPT industry standard interface. Its high tolerance fit ensures excellent sealing performance, and there is no need to use excessive sealant during installation, which greatly improves the efficiency of field equipment maintenance.

IMT diesel pressure gauges use industry-leading laser welding technology to achieve an integrated seal between the stainless steel housing and the connector. Compared with the common pressure ring seals on the market, our structure has a 95% reduction in oil leakage under long-term high-frequency vibration environment, and the accuracy drift is less than 0.5 after 20,000 pressure fatigue tests, ensuring extremely high reliability in industrial-grade applications. As a source factory, IMT can customize the diaphragm material according to the customer’s specific application scenario (such as low sulfur diesel or biodiesel). Our products not only compare with international big names in precision, but also shorten the delivery cycle by 40%, which solves the contradiction between “quality stability” and “uncontrollable delivery time” in mass procurement for B2B customers.




These purchasers need to integrate the pressure gauge into the diesel generator panel. IMT provides customized dial Logo service and stable batch supply, helping manufacturers to improve the professional image and durability of the whole system.

In the face of high salt spray and high vibration engine room environment, engineers need internationally certified and corrosion-resistant instruments. IMT products can effectively monitor the pressure of the propulsion system and prevent the failure of the fuel system during the sea voyage.

responsible for the daily maintenance of Caterpillar, Cummins and other equipment. IMT provides standardized replacement parts with high accuracy to help service technicians quickly locate fault points such as fuel pump leakage or filter element blockage.

In large plant fuel supply stations or refueling systems, integrators need pressure monitoring tools with high protection levels. IMT’s IP65 protection standard ensures long-term accuracy in open air cleaning or in bad weather.


ensure that the system is in a shutdown and no pressure state, and check the NPT threads for scratches.

It is recommended to use a small amount of raw material tape to wrap the joint and screw it into the mounting hole clockwise to avoid excessive force.

After installation, please set the rubber plug on the top of the instrument to the OPEN position to eliminate the internal pressure caused by the temperature difference.

It is recommended to check the accuracy every 6 to 12 months to ensure that the diesel system operates in a safe range.
