Description

The Model I14-02 Diaphragm Actuated Piston Differential Pressure Gauge offers precise and durable differential pressure measurement with advanced diaphragm-actuated piston design. Available in dial sizes DN63, DN100, and DN150 (2.5″, 4″, and 6″), it covers ranges from 0-1 bar to 0-10 bar with ±2% accuracy (CL 2 ascending F.S.). The gauge supports inline, bottom, and back port mounting, featuring a standard 1/4″ NPT (female) process connection and IP65 ingress protection. Available in fillable or dry execution, its wetted parts include SS316 body, SS302 spring, ceramic magnet, Teflon seal, Viton diaphragm, and SS316L piston for reliable performance. It also offers an electric rating with a Reed Switch (SPDT) housed in a flameproof head certified for IIA, IIB, and IIC explosive atmospheres, ensuring safe operation in hazardous environments.

What People Say About Our Product


Customers consistently praise our temperature and pressure gauges for their accuracy, durability, and ease of installation. From HVAC professionals to industrial users, many highlight the clear readings and reliable performance under tough conditions. Whether for home systems or heavy-duty applications, our gauges are trusted for getting the job done right.

A temperature and pressure (T&P) gauge is used to monitor both the temperature and pressure levels within systems like boilers, water heaters, HVAC units, and other pressurized equipment. It helps ensure the system is operating safely and efficiently.

Installation typically involves threading the gauge into a designated port on the system (usually a 1/4" or 1/2" NPT fitting). Always ensure the system is depressurized before installation and use thread sealant to prevent leaks. Refer to the product manual for specific instructions.

For best performance, it’s recommended to check calibration annually, especially in industrial or high-usage environments. Replace the gauge if you notice inaccurate readings, a stuck needle, or visible damage to the dial or housing.

Our Product Review

This pressure gauge is spot-on accurate and durable. I installed it on a boiler system for a commercial client, and it’s been holding up perfectly under high pressure and heat. The stainless steel casing is rugged, and the glycerin fill really helps reduce needle vibration. Definitely a professional-grade product worth the price

Industrial Pressure Gauge

Very reliable temperature readings and the digital display is easy to read even in low light. I use it for monitoring HVAC systems and it has made diagnostics much quicker. The only downside is that the battery compartment is a bit tricky to open, but overall, it’s a solid product.

Digital Temperature Gauge

I’ve been using this temperature and pressure gauge for a few months on my residential boiler system, and it’s performed consistently well. The readings are accurate, and the dual-scale display is easy to interpret. It was easy to install and fit perfectly into the existing port. Build quality feels solid with a brass connection and clear lens. So far, it's been reliable under both high-temp and high-pressure conditions. I’ll be purchasing more for future installs.
