206/5000
Air Tank Pressure Gauge is designed for heavy-duty industrial compressors and gas tank systems and is manufactured in strict compliance with ASME B40.100 standards. The product uses a CNC precision machined H59 brass movement combined with a phosphor bronze Bourdon tube and has passed more than 100,000 pressure cycle fatigue tests. Even under the condition of high frequency vibration, it can still maintain the full range accuracy of ± 1.6% or ± 2.5%. With IP54 protection level, the shell is effectively resistant to oil and dust, and is ideal for low repair rate and long-term stability.

High durability movement
The transmission mechanism adopts H59 brass, the gears are processed by micron-level hobbing technology, and the bite gap is controlled within 0.05mm. The wear rate is reduced by 60%.
Anti-overload Bunden Tube
The core pressure sensing element is made of C51900 phosphor bronze alloy with cold work hardening treatment. The Air Tank Pressure Gauge can withstand transient overpressure impacts without deformation.
anti-vibration performance
In view of the compressor working environment, we have added high viscosity damping oil to the movement. At the industrial vibration frequency of 20-50Hz, the pointer jitter amplitude is less than ± 0.5 lattice.
Weather resistant dial
The dial is made of aluminum alloy, and the shell has undergone a 24-hour salt spray test. In a humid or salty coastal industrial environment, the appearance is not rusted and the inventory life is extended.
Zero leakage sealing
The threaded interface (NPT/BSP) of each Air Tank Pressure Gauge is tested by 100% stop gauge, and the tolerance is controlled at 6g accuracy. The leakage rate of air tightness test is lower than 0.01 mbar · l/s.
100% Full Inspection
Reject sampling mode. Before leaving the factory, each 1 instrument has been calibrated at 0%, 50% and 100 on the calibration table, and the unpacking defect rate (DOA) is strictly controlled within 500 PPM.
Manufacturing Process
Forming and heat treatment
The raw material copper pipe is precisely formed into C- type or spiral type by pipe bender. Subsequent 300°C annealing ensures that the Air Tank Pressure Gauge long-term readings do not drift.
Automatic argon arc welding
The combination of the connector and the Boughton tube adopts the automatic TIG argon arc welding process. The welding current control accuracy is ± 1A to ensure that the weld is uniform and free of pores.
Pressure calibration and sealing
After assembly, the instrument is sent to a computer-controlled pressure calibration station. The system automatically pressurizes to full scale and returns to zero, repeating 3 times to eliminate mechanical hysteresis.

Housing Materials (ABS Plastic / Chrome Plated)
Supply chain cost optimization
Relying on a mature raw material procurement system, we have effectively reduced manufacturing costs. Under the same precision standard, our wholesale price is 30% lower than that of European and American brands.
Adapt to extreme working conditions
Different from ordinary civilian instruments, our industrial-grade pressure gauges use special grease and high-elastic seals, and the operating temperature range covers -40°C to 70°C.
After-sales technical support
We create exclusive technical profiles for our distributors. If an Air Tank Pressure Gauge selection or failure problem is encountered at the end user, the technical team can provide a troubleshooting report or 8D report.
For standard specifications (such as 2-inch dial, 1/4 NPT,0-200 PSI), the MOQ is as low as 100. For OEM orders with Logo customization, MOQ is usually 500 to share the plate making cost.
We adopt industrial shockproof packaging. Each pressure gauge has an independent inner box, and every 50 pressure gauges are packed into a thickened corrugated paper outer box, and cushion air column bags are added between the outer boxes and palletized. Historical data show that the transport breakage rate is less than 0.1 per cent.
The standard Air Tank Pressure Gauge contains a trace of oil and is suitable for inert gases such as air and nitrogen. If used for oxygen, it must be stated in the order that we need to perform a special “no oil cleaning” process to meet oxygen service safety standards.
Standard models are well stocked and can be shipped within 3-5 days. Custom Logo or special specifications of the order, usually the production cycle is 20-25 days. Emergency orders can apply for priority scheduling.
Yes, we can provide the factory certificate with the goods. If a third-party CNAS or NIST traceable calibration certificate for a specific serial number is required, we can handle it on our behalf at an additional cost.
We offer a 12-month quality warranty (from the date of shipment). If there are non-human damage quality problems (such as air leakage, accuracy failure) during the warranty period, we will provide 1:1 replacement service for free and reissue it in the next batch of orders.
