Auburn H4-12-12PK Gauge Glass
The Auburn H4-12-12PK Gauge Glass is a high-performance borosilicate glass solution designed for critical fluid monitoring in industrial boilers and steam engines. This heavy-duty sight glass features a 5/8" outer diameter (OD) and a 12-inch length, providing exceptional thermal shock resistance and durability under high-pressure conditions. Each 12-pack contains high-clarity tubes equipped with a distinct red line indicator, which uses optical magnification to make colorless liquid levels easily readable from a distance.
Engineered for seamless integration, the H4-12-12PK serves as the direct replacement gauge glass for discontinued or older models, including the H4-12 and H4-13 series. The fire-polished ends offer superior safety by reducing the risk of fractures during installation in low-pressure boilers, reservoirs, and condensate return tanks. Whether you are performing routine maintenance or a complete system overhaul, these 5/8" OD red line tubes ensure reliable, high-visibility performance for trade professionals in HVACR and plumbing sectors.
This item is not eligible for free shipping.
Key Benefits
- Enhanced Visibility: Features a high-contrast red line that magnifies in the presence of liquid for rapid level checks.
- Robust Material: Manufactured from premium borosilicate 3.3 glass to withstand significant thermal expansion and pressure.
- Precise Fit: Standard 5/8" OD and 12" length ensure compatibility with a wide range of industrial water gauge valves.
- Safe Handling: Fire-polished edges minimize micro-cracks, enhancing the structural integrity and longevity of the tube.
- Bulk Value: Convenient 12-pack configuration provides a ready supply for large facilities and frequent maintenance schedules.
Common Questions
Is this gauge glass compatible with high-pressure steam systems?
Yes, the Auburn H4-12-12PK is designed for industrial applications, but always verify your system's specific PSI and temperature ratings against the technical limits of borosilicate glass for your safety.
Does the red line work with colored liquids?
The optical magnification effect is most effective with colorless or clear liquids, though the red stripe remains a highly visible reference point for all fluids.
What does the 12-pack include?
This package includes twelve individual 12-inch glass tubes. Please note that gaskets and gauge valves are typically sold separately unless specifically bundled.
