4" 100mm Stainless 316 Pressure Gauge | 0-0.7MPa/0-700psi | Bayonet Ring for Shock Resistance
Professional-Grade Stainless Steel Gauge
Our 4-inch (100mm) Stainless Steel Pressure Gauge is engineered for precision and durability in demanding industrial settings. Featuring a 0-0.7MPa / 0-700psi dual-scale dial, this instrument is constructed entirely from corrosion-resistant 316 stainless steel and incorporates a unique bayonet ring for enhanced security and shock-proof performance. Designed for reliability, this bayonet pressure gauge ensures stable readings and long service life in challenging environments.
Key Features & Benefits
Premium 316 Stainless Steel Construction: Offers exceptional resistance to corrosion, chemicals, and harsh weather conditions, making this stainless steel pressure gauge ideal for marine, chemical, and food processing applications.
Secure Bayonet Ring Design: The exclusive bayonet ring provides a locked, tamper-resistant front assembly. This feature makes it a true shock proof pressure gauge by preventing the window from loosening due to vibration or impact.
Clear Dual-Scale Readability: The large 4-inch dial displays both metric (0-0.7MPa) and imperial (0-700psi) units, providing flexibility and eliminating conversion errors for operators.
Enhanced Safety & Durability: The combination of solid front design and bayonet locking ring contains potential internal overpressure events and protects against environmental ingress (dust, moisture).
Versatile Mounting: Standard radial bottom connection for easy installation on panels, pipelines, or equipment skids.

Why the Bayonet Ring Makes a Superior Shock Proof Gauge
The bayonet pressure gauge design represents a significant advancement over standard screwed bezels:
Vibration-Proof Locking: The quarter-turn bayonet mechanism ensures the front ring cannot vibrate loose, a critical failure point in high-shock environments.
Quick Maintenance: Allows for faster and tool-free disassembly for cleaning or inspection compared to threaded bezels, while maintaining a secure seal.
Tamper Resistance: Provides an additional level of security against unauthorized adjustment or disassembly in regulated or public settings.
Reliable Seal: Maintains a consistent, even pressure on the gasket for superior sealing against moisture and dust ingress.
Typical Applications
This robust stainless steel pressure gauge is perfectly suited for:
Marine & Offshore Equipment
Chemical & Petrochemical Processing Plants
Food & Beverage Production Lines (Sanitary Applications)
Pharmaceutical and Water Treatment Facilities
Power Generation and Utility Systems
High-Vibration Machinery and Mobile Equipment
