Product details
Weiss Industrial Gauge | 4PG-1 | 4.5″ Dial | 0-160 PSI/KPA
Product Description
The 4PG-1 series is engineered for durability in demanding environments. This model features a dual-scale range of 0-160 PSI (0-1100 KPA), which is the most common pressure range used for monitoring domestic water booster sets, chilled water secondary pumps, and industrial air headers in Dubai and Abu Dhabi.
The oversized 4.5-inch (115 mm) dial is housed in a rugged, high-impact polypropylene case, providing excellent resistance to the chemicals and humidity found in plant rooms. The internal movement is crafted from precision brass, and the 1/4″ NPT lower mount (bottom) connection allows for straightforward installation into standard industrial manifolds.
Key Features
- Superior Visibility: The 4.5″ dial face allows for easy and accurate reading from a distance, making it ideal for large-scale plant rooms.
- Dual Scale Readout: Simultaneously displays PSI and KPA, satisfying international project requirements in the Middle East.
- ASME Grade A Accuracy: Offers $\pm$1% accuracy across the full scale, providing more precise monitoring than standard utility gauges.
- Corrosion-Resistant Case: The high-impact polypropylene housing is designed to withstand the harsh conditions of UAE mechanical rooms.
- Reliable Brass Internals: Features a precision-engineered brass Bourdon tube and socket for consistent performance with non-corrosive media.

Frequently Asked Questions
- Q: Why is the case made of polypropylene?
- A: Polypropylene is a high-performance polymer that does not rust or corrode in humid environments, making it more durable than traditional steel cases in many industrial plant settings.
- Q: Can this be used for compressed air?
- A: Yes, the 160 PSI range is perfectly suited for industrial compressed air systems.
- Q: Is there a liquid-filled version for this size?
- A: Yes, Weiss offers the 4PGL series if you require a liquid-filled gauge to handle high vibration or pressure pulsations.
