Product Description
4" 100mm All Stainless Steel Pressure Gauge | 0-1.6MPa/230psi | Vibration Resistant (No Oil Fill)
Corrosion-Resistant Precision for Harsh Environments
Our 4-inch (100mm) All Stainless Steel Pressure Gauge is engineered for reliability in the most demanding conditions. Featuring a 0-1.6MPa / 0-230psi range, this rear entry pressure gauge is crafted entirely from corrosion-resistant stainless steel, making it perfect for chemical, marine, and food processing applications. Unlike a silicone oil filled pressure gauge, it achieves superior vibration resistance without any internal fill fluid, thanks to precision engineering and advanced material treatment of the Bourdon tube.
Key Features & Benefits
- Full Stainless Steel Construction: Every component is made from high-grade stainless steel, providing maximum resistance to corrosion, acids, alkalis, and saline atmospheres. This is a true, durable pressure gauge stainless steel solution.
- Engineered Vibration Resistance (No Oil Fill): Achieves excellent resistance to vibration and pulsation without being a silicone oil filled pressure gauge. This eliminates risks of fluid leakage, is suitable for wider temperature ranges, and is ideal for applications where oil-fill is not permitted (e.g., certain food, oxygen, or clean processes).
- Long-Term Accuracy & Durability: The core Bourdon tube undergoes specialized over-pressure proofing and aging treatment. This process stabilizes the metal, ensuring the gauge maintains its calibrated accuracy over a much longer service life, even under fluctuating pressure conditions.
- Reliable Rear Entry Design: As a standard rear entry pressure gauge, it offers versatile and straightforward installation on panels, pipes, or equipment with a bottom or back connection point.
- Maintenance-Free Operation: The sealed, dry design requires no maintenance or risk of fill fluid degradation, offering a truly "fit and forget" installation.

Why Choose This Over a Silicone Oil Filled Gauge?
While a silicone oil filled pressure gauge is common for damping, this model provides a superior solution for specific needs:
- No Leak Risk: Eliminates potential contamination of your process media from internal fill fluid leaks.
- Wider Temperature Range: Performs consistently in environments where oil viscosity changes could affect performance.
- Clean & Compliant: Perfect for sanitary, oxygen service, or ultra-clean applications where introducing any fluid is unacceptable.
- Low Maintenance: No need to check or refill damping fluid.
Typical Applications
This rugged, dry pressure gauge stainless steel is ideal for:
- Chemical Processing and Pharmaceutical Plants
- Offshore & Marine Equipment
- Food & Beverage Production (Sanitary Applications)
- Water Treatment and Desalination Facilities
- Pulp & Paper Industry
- Any application requiring a durable, corrosion-resistant gauge without fluid fill
