Tubular Gauge Glass - Standard Wall (7/64") Red Line - Package of 6 (0.625, 5/8, Inches, 10.25, Inches)

The Zight 3.3 Borosilicate Level Gauge Tube is a high-performance transparent sight glass tube designed for accurate liquid level measurement in industrial applications. Made from premium borosilicate glass 3.3, this gauge glass tube provides outstanding resistance to thermal shock, chemical corrosion, and mechanical stress. Engineered for use in boilers, pressure vessels, reactors, storage tanks, expansion tanks, and process equipment, this level gauge tube delivers long-term reliability under demanding operating conditions. Its superior clarity allows for easy visual monitoring of fluids such as water, steam, condensate, chemicals, ammonia, and process liquids. Manufactured by Zight, a trusted supplier of industrial sight glass solutions, this borosilicate level gauge tube meets the requirements of modern process industries where safety, accuracy, and durability are critical.

• Clear & Accurate Level Indication: Use of distinct red and white lines along its length to provide refracted magnification and stark contrast against the color of the fluid or background making it easier to identify fluid levels at a glance. Optical clarity that ensures precise liquid level visibility in boilers, tanks, reactors, and expansion vessels.
• Standard Wall (7/64"): Suitable for low-pressure situations where the internal pressure is within the glass’s capacity.
• Premium 3.3 Borosilicate Glass: Manufactured by Zight, this level gauge tube offers excellent resistance to heat, pressure, and chemical attack, making it ideal for industrial fluid level monitoring.
• Chemical-Resistant Sight Glass Tube: Resistant to water, steam, oils, acids, alkalis, ammonia, and many industrial chemicals.
• Industrial Replacement Gauge Glass: Designed as a direct replacement for standard transparent level gauge tubes used in power, chemical, food, and water treatment industries.
