Weiss HVAC Pressure Gauge | 4CTS/100PK | 4.5″ Dial | 0-100 PSI/KPA
Product Description
The 4CTS/100PK is part of the specialized Weiss CTS series, engineered for general service conditions where a balance of precision and field durability is required. The “4CTS” designation identifies this as a 4.5-inch (115 mm) Stainless Steel Case gauge with a Lower (Bottom) Mount connection. This model features a dual-scale dial displaying 0-100 PSI and 0-700 KPA.
In the UAE market, the 100 PSI range is the most common specification for domestic water supply lines, residential booster pumps, and secondary chilled water loops in Dubai and Abu Dhabi. The drawn stainless steel case provides a superior aesthetic and enhanced corrosion resistance compared to standard black-painted steel gauges, while the 1/4″ NPT brass connection ensures compatibility with standard regional piping.
Key Features
- Durable Stainless Steel Case: The polished 304 SS case is moisture-resistant and rust-proof, ideal for the high-humidity plant rooms of the Middle East.
- Large 4.5″ High-Visibility Dial: Features an oversized face with high-contrast black lithographed graduations on a white background for easy reading at a distance.
- Precision Movement: All-brass internal construction with a precision gear and pinion system ensures consistent, long-term accuracy.
- Dual Scale (PSI/KPA): Simultaneously displays pressure in both imperial and metric units, satisfying international project requirements in the UAE.
- Slotted Adjustable Pointer: Allows for easy field calibration and zero-adjustment to maintain accuracy over time.

Frequently Asked Questions
- Q: Is this gauge suitable for steam service?
- A: Yes, but it must be protected from high temperatures by installing a coil-type siphon (pigtail) between the gauge and the steam line.
- Q: Can it be used for outdoor pump sets?
- A: The stainless steel case and Lexan window are highly resistant to the UAE’s intense sunlight and humidity.
- Q: Does this gauge have a front flange for panel mounting?
- A: No, the 4CTS is a stem-mounted gauge. For surface/panel mounting with a back flange, you would require the 4CTA
