    Image of Product. Front orientation. Sights. Sights for Quick-Clamp Sanitary Tube Fittings, 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.
