Extra-Heavy Wall Tubular Gauge Glass

John Moncrieff Ltd supplies extra-heavy wall tubular gauge glass engineered to perform under extreme pressure conditions — delivering consistent, reliable liquid level indication in the most demanding industrial environments.

Built for applications requiring the highest mechanical integrity, this gauge glass can withstand working pressures of up to 600 psi (≈ 41 bar). The increased wall thickness ensures exceptional strength, impact resistance, and long-term service life even under harsh operating conditions.

Technical Specifications

• Pressure Rating: Up to 600 psi (≈ 41 bar)
• Available Diameters: 5/8" and 3/4"
• Standard Lengths: Up to 48" (custom sizes available on request)
• Material: High-strength borosilicate glass for superior durability
• Configuration: Straight tubular format for vertical and horizontal installations

Enhanced Visibility Options

For improved level detection, red and white meniscus line models are available. These versions enhance contrast, allowing operators to easily read liquid levels even in low-light or high-vibration environments.

Applications

• High-pressure process vessels
• Steam boilers and industrial heating systems
• Petrochemical and refining operations
• Power generation and utility systems
• Heavy-duty fluid storage and level monitoring applications

With over a century of glass manufacturing excellence, John Moncrieff Ltd continues to provide high-pressure gauge glass solutions built for performance, reliability, and operational safety.
