Sights for Quick-Clamp Sanitary Tube Fittings

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

Plastic Window with 304 Stainless Steel Ring

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).

304 stainless steel sights have a ring that's embedded around their shatter-resistant plastic window. This design protects the sights from chipping or cracking while under the stress of the quick-clamp fitting. All withstand harsh cleaners and sanitizers for clean-in-place (CIP) and steam-in-place (SIP) applications. They do not contain Bisphenol A (BPA), Bisphenol B (BPB), or BPA derivatives (BPX), which are chemicals that can contaminate your process lines. All meet ASME BPE design standards for bioprocessing equipment that ensure purity and safety.

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.

Level Indicators with Shut-Off Valve

316 Stainless Steel With Automatic Shut-Off

Shut-off valves stop flow so you can clean and replace gauge glass without removing these indicators from your equipment.

316 stainless steel indicators are more corrosion resistant than brass indicators.

Indicators with automatic shut-off will temporarily close if the gauge glass breaks. The valves must be closed manually for permanent shut-off.

Monitor liquid level in applications that have vibration, high pressures, and high temperatures. These indicators have steel chambers, glass windows, and seals made of fiber and SBR rubber to resist corrosion and withstand higher temperatures than other level indicators. Use them with a wide variety of liquids, such as petroleum, chemicals, and natural gas. All meet ASME BPVC.VIII.1 safety standards for pressure vessels, so they’re approved for use in low-pressure water and steam applications too. They’re also known as armored level gauges.

Indicators with reflex glass show the level of liquid behind the glass, but not the liquid’s color or any particulates in it.

Indicators with transparent glass help you monitor a liquid’s color and particulates, as well as its level. Use two pieces of this glass in your indicator; the liquid flows between them, so you see straight through. Instead of one continuous vision slot, there are cross ties that divide it to better support the chamber.

Add shut-off valves to stop flow with the turn of a wheel. They help you access indicators in order to clean or replace the glass or the entire indicator. These valves also stop flow automatically if the indicator glass breaks, preventing the loss of fluid. However, for permanent shut-off you must close them manually. Put one valve on top of your indicator and one on the bottom for a 90° connection between the indicator and your tank. To connect the female threads on your indicator to the female gauge threads on the shut-off valve, use a male pipe nipple (not included).
