4 Inch 100mm Stainless Steel Pressure Gauge Vibration Resistant Corrosion Resistant No Oil Fill Manometer

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
