Ordered as 4MRF8, this is a Reflex Gauge Glass. The gauge glass provides a flat, pressure-rated viewing window for liquid level indication.
As a material, Borosilicate gauge glass is valued for precision-formed bore and wall thickness, annealed for consistent strength. This material stands up to internal pressure, thermal shock, and chemical attack from water and steam. Exposure to service beyond the rated pressure and temperature or mechanical impact will shorten service life.
You will find this material specified across food and beverage processing, water treatment, and process tanks and vessels.
Reference part number 4MRF8 when ordering; the item is sold individually. As always, verify media compatibility and operating conditions against the requirements of your specific application.
