Yes, they are designed to withstand moderate to high pressures and temperatures up to around 200°C.
AL Jazeera PTFE of Dubai, UAE, is one of the key producers of superior quality PTFE Lined Window Sight Glasses, which provide safe and unhindered visual inspection of fluid movement in hostile chemical processes. They are experts at manufacturing a huge variety of PTFE-lined parts such as sight glasses, valves, spools, elbows, and customer-specific fittings. These products are designed to withstand corrosion, chemical attack, and elevated temperatures and are best suited for application in chemical processing, pharmaceuticals, petrochemicals, and wastewater treatment industries.
PTFE Lined Window Sight Glass is an observation unit mounted on pipes or process equipment so that operators can see the flow of corrosive or dangerous fluids. It has a long-lasting metal casing, chemically inert PTFE lining, and a toughened glass observation panel. The PTFE lining provides chemical resistance to the inner surface, while clear glass provides uninterrupted visual observation. These sight glasses play a vital role in ensuring safety and control within corrosive fluid handling systems.

PTFE lining ensures high resistance to a wide range of corrosive chemicals, making it suitable for aggressive environments.
The non-stick properties of PTFE prevent material build-up, ensuring clear visibility and reducing maintenance needs.
PTFE can withstand extreme temperatures, maintaining its performance in both high and low thermal conditions.
PTFE-lined components resist wear and degradation, providing a long-lasting solution in industrial processes.
It allows visual monitoring of fluid flow in pipelines, especially in corrosive chemical processes.
They typically consist of a metal body, PTFE lining for corrosion resistance, and a toughened borosilicate glass window.
They are used in chemical processing, pharmaceuticals, petrochemicals, food processing, and wastewater treatment plants.
Yes, they are designed to withstand moderate to high pressures and temperatures up to around 200°C.
Minimal maintenance is needed; periodic inspections for glass clarity and lining integrity are recommended.
