Core Feature

1

outstanding material advantages

 

It is made of military grade brass,which possesses excellent corrosion resistance and mechanical strength.

Anti vibration design ensures that the pointer remains stable and does not shift during transportation and usage.

Special sealing technology,eliminating the risk of leakage.

2

precision manufacturing technology

 

CNC precision processing ensures the accuracy of the thread fit.

Precise movement,with accurate and reliable measurement.

Dual color dial design,with the pressure area clearly visible(green indicates the normal area).

3

Broad compatibility

 

Multiple specifications and thread combinations,compatible with over 90% of fire extinguisher brands.

The specially designed M10*1-12.5 thread solves the problem of matching special interfaces.

The NPT thread version perfectly matches the American standard fire extinguisher.

Purchase Guide

How to Choose the Right Model

1.Measure the diameter of the original pressure gauge: Use a caliper to measure the outer diameter of the dial.
2.Confirm the thread specification:

• M8×1: Commonly found in small portable fire extinguishers
• M10×1: Main specification of medium-sized fire extinguisher
• 1/8 NPT: Special for American Standard Fire Extinguishers

3.Take environmental factors into consideration: In humid environments, it is recommended to choose the nickel plated version.

Recommended combination

• Φ35mm + M10×1: The most versatile, suitable for 4-8kg dry powder fire extinguishers
• Φ25mm + M8×1: Suitable for 2-3kg small fire extinguishers
• Φ37mm + 1/8 NPT: The ideal choice for American standard fire extinguishers

FAQ

Q: How can one determine if a replacement is necessary?
A: If the pointer fails to return to zero, the dial becomes blurry, there is leakage, or the pointer gets stuck, then it is necessary to replace it immediately.

Q: What do the different colored pressure areas represent?
A: Green (1.0 - 1.4 MPa) indicates normal pressure; red (below 1.0 or above 1.4) indicates abnormal pressure.

Q: Is it necessary to apply sealant during installation?
A: It is not recommended. Our product comes with high quality sealing gaskets. Applying additional sealant may affect the sealing effect.

Q: Will brass material rust?
A: High quality brass has excellent corrosion resistance and is unlikely to rust under normal usage conditions. In humid environments, a nickel plated version can be chosen.
