Low-Pressure Differential Gauges with U-Tube
Also known as manometers, these gauges come with indicating liquid that moves up and down two columns—the difference in height between them is your pressure. They are commonly used to indicate clogged filters.
- For Use With: Acetylene, Air, Argon, Carbon Dioxide, and Steam
- Accuracy: Not Rated (Not Graded)

Level Indicators with Shut-Off Valve
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.
Use indicators with stainless steel drain valve on expansion tanks.
Indicators with needle stem have a stem in the lower shut-off valve to clear the orifice as the valve closes.
Indicators with automatic shut-off will temporarily close if the gauge glass breaks. The valves must be closed manually for permanent shut-off.

Sights for Quick-Clamp Sanitary Tube Fittings
Gasket, Quick-Clamp Fitting, And
Tube Fitting (All Sold Separately)
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
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.
