Sights for Quick-Clamp Sanitary Tube Fittings

Sight Shown Assembled With
Gasket, Quick-Clamp Fitting, And
Tube Fitting (All Sold Separately)

Glass Window with 2205 Stainless Steel Ring

Monitor food, brewery, chemical, pharmaceutical, and biotech processing lines with these sights that attach to quick-clamp fittings for fast installation and easy removal for cleaning. All have a one-piece design, so there are no crevices where bacteria can grow. A quick-clamp fitting, gasket, and tube fitting are required (sold separately).

For superior strength and reliability, choose 2205 stainless steel sights. All have a glass window that’s melted around a high-strength ring, so they won’t shatter, leak, or lose their shape under high pressure, heat, chemicals, or impact. They withstand harsh cleaners and sanitizers for clean-in-place (CIP) and steam-in-place (SIP) applications. USP Class VI and TUV Rheinland Certified, these sights meet safety standards in the U.S. and Europe. They also meet DIN standards for glass materials used in sights, ASTM standards for materials used in boilers and pressure vessels, and ASME BPE design standards for bioprocessing equipment that ensure purity and safety.

Sanitary Level Indicators

Mount these indicators on the outside of tanks in food, pharmaceutical, and other sanitary environments to monitor their liquid levels. Made from 316 stainless steel, they will not corrode from frequent washdowns with harsh cleaners and sanitizers. Rounded edges and polished surfaces prevent the risk of bacteria growth. These indicators have an impact-resistant polycarbonate shield that protects the glass window while still letting you see the liquid level. The liquid level inside these indicators matches the level in your tank, making it easy to view readings at a glance. Attach these indicators to tanks with quick-clamp sanitary fittings for fast installation and easy removal for cleaning or moving them.

Flow Sights for Food and Beverage

Made of FDA-listed materials for use with food and beverage, these sights have sanitary quick-clamp connections and an electropolished 316 stainless steel body for easy disassembly and cleaning. They meet USP (United States Pharmacopeia) Class IV standard for food applications. Sights let you visually confirm flow and inspect liquid color and clarity. Backlight the back window to increase the visibility of dark liquids.
