40mm Medical Pressure Gauge 25 Psi Acrylic Lens Brass Socket For Anesthesia Equipment
40mm Medical Pressure Gauge 25 PSI Acrylic Lens Brass Socket EN 837-1 for Anesthesia Equipment
Product Overview
The 40mm medical pressure gauge is a compact mechanical Bourdon tube instrument designed for low-pressure monitoring in anesthesia equipment and medical gas systems. It provides stable analog pressure indication up to 25 PSI, making it suitable for precise control of breathing circuits, oxygen delivery systems, and medical inflation devices.
Manufactured according to EN 837-1 standard, this gauge ensures consistent mechanical performance and reliable measurement in critical medical environments where stability and readability are required.
The compact 40mm dial design, combined with an acrylic lens and brass socket connection, makes it ideal for space-limited medical equipment integration.

Key Advantages
1. Stable Low Pressure Measurement (25 PSI)
Designed for precise control of low-pressure medical gas systems including anesthesia and respiratory applications.
2. EN 837-1 Mechanical Standard
Manufactured according to international pressure gauge standards ensuring consistent structure and measurement reliability.
3. Compact 40mm Design
Small dial size enables integration into space-limited medical devices and portable equipment.
4. Acrylic Protective Lens
Provides clear visibility and basic protection for medical environments with frequent operation.
5. Brass Socket Structure
Ensures stable connection with medical gas systems and standard pneumatic interfaces.
Working Principle (Bourdon Tube)
The Bourdon tube deforms elastically when pressure is applied. This mechanical movement is transferred to a pointer system, allowing direct analog pressure reading without electrical power.
Installation Notes
- Use PTFE tape for sealing threaded connection
- Ensure correct radial mounting orientation
- Avoid over-tightening during installation
- Suitable for medical gas and anesthesia systems only
