Product details
Weiss Pressure Gauge | 4PGN | 4″ Dial | 0-300 PSI/BAR
Product Description
The 4PGN series is part of the premium Weiss industrial line, offering superior durability compared to standard utility gauges. The “4” indicates a 4-inch (100 mm) dial size, providing a large, clear display for accurate readings at a distance. The “PGN” designation typically refers to a Glycerine-Filled (or fillable) stainless steel case, which is critical for applications involving high vibration or pressure pulsations common in Dubai and Abu Dhabi’s industrial sectors.
This model features a wide pressure range of 0 to 300 PSI (0 to 20 BAR). This range is the industry standard for High-Rise Booster Systems, pump discharge monitoring, and high-pressure chilled water systems. The stainless steel case provides excellent protection against the harsh, saline air of the Middle East, ensuring a long service life without corrosion.
Key Features
- Glycerine Fillable Case: Designed to be filled with dampening fluid to eliminate pointer flutter and protect internal movements from vibration.
- Corrosion-Resistant Stainless Steel Case: Provides maximum protection against the elements, making it ideal for both indoor and outdoor installations in the UAE.
- Dual Scale (PSI/BAR): Displays pressure in both imperial and metric units, complying with international engineering standards and local building codes.
- High-Precision Internals: Features a high-quality Bourdon tube and movement for consistent accuracy and smooth needle travel.
- Standard Connection: Features a 1/4″ NPT (or optional 1/2″) connection, suitable for a wide variety of industrial manifolds and pipes.

Frequently Asked Questions
- Q: Why is the “PGN” series better for pumps than the “TL” series?
- A: The PGN series features a stainless steel case that can be liquid-filled. This prevents the needle from shaking (fluttering) due to pump vibration, which can wear out a standard dry gauge very quickly.
- Q: Can this be used for chemical applications?
- A: If the chemicals are non-corrosive to copper alloys, yes. For aggressive chemicals, we recommend the Weiss LF4UGY series with 316 Stainless Steel internals.
- Q: Does this gauge require a siphon?
- A: Only if used for steam service. For water, air, or oil, it can be mounted directly.
