Sights for Quick-Clamp Sanitary Tube Fittings

Sight Shown Assembled

With 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 quick-clamp fitting, gasket, and tube fitting are required (sold separately).

Plastic with Plastic Window

Sights that are made entirely of plastic have a shatter-resistant window.

304 Stainless Steel with Plastic Window

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.

2205 Stainless Steel with Glass Window

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.

High-Vacuum Sights for Quick-Clamp Fittings


Sight Shown Assembled with Tube Fitting, Ring, and Clamp (All Sold Separately)

Designed with quick-clamp (KF) connections, these sights connect to a port on a high-vacuum chamber, so you can monitor what's happening inside. A sleeve seals the glass window to the body of the sight to prevent leaks. To connect to your chamber, you'll need a clamp and a ring (sold separately). Not for use in pressure applications.
