Quick-Clamp Inline Pipe Sight Glass
Borlan Fluid quick-clamp inline pipe sight glass provides a transparent viewing section between two clamp-end connections. Use it to visually check liquid flow, color, clarity and bubbles in a compatible process line. Reference dimensions are listed below; connection standard, materials, seals and operating limits must be confirmed for the final order.
Quick-clamp inline pipe sight glass gives operators a direct view into a process line. The transparent chamber sits between two clamp-end connections, so liquid flow, color, clarity and visible bubbles can be checked at the point of installation. Borlan Fluid supplies this style for projects that need a compact in-line viewing section and a connection matched to the surrounding pipework.
Product Views
The clear cylindrical chamber, end ferrules and external tie rods are visible in the actual product photos. The clamp ends must be matched to the mating ferrules, gaskets and clamps specified for your line.

Where It Helps
- Visual flow checks: observe whether liquid is moving through the pipe section.
- Process observation: inspect visible color changes, clarity and entrained bubbles without opening the line.
- Connection planning: use the clamp-end layout to plan a removable viewing point in a compatible pipe run.
The sight glass is an observation component. It does not measure flow rate or replace a process instrument.

Selection note: reference chart values are nominal and may vary with the final construction. Confirm the selected size and connection against an approved Borlan Fluid drawing before fabrication or ordering.
What to Confirm Before Ordering
- Pipe size, mating clamp/ferrule standard and required B dimension.
- Available installation length and required overall A dimension.
- Wetted metal grade, transparent tube material and seal material for the process fluid.
- Design pressure, operating temperature, cleaning method and documentation requirements.
- Whether clamps and gaskets are included in the requested supply scope.
These details determine the final configuration. Material grades, ratings and sanitary suitability should be confirmed for the exact order rather than assumed from a product photo.
Frequently Asked Questions
Can this sight glass show the liquid inside a closed pipe?
Yes. Its transparent section is intended for direct visual observation of the fluid in the line. The useful view depends on the fluid, lighting and installation position.
Are the listed sizes interchangeable with every sanitary clamp standard?
No. Similar size names can use different ferrule dimensions. Provide the mating connection drawing or standard so Borlan Fluid can confirm fit.
Are pressure and temperature limits the same for every size?
No rating is stated for this reference table. The allowable conditions depend on the selected tube, seals, metal parts and assembly design. Request the approved specification for your configuration.
