High-Polish Metal Quick-Clamp Sanitary Tube Fittings

- Temperature Range: See Gaskets
The smooth finish inside these fittings makes it easy to remove product residue. Also known as aseptic and tri-clamp fittings, they connect with a gasket, a clamp, and another quick-clamp fitting for a fast and easy way to access your line. The pressure rating of the fitting will vary depending on the clamp you choose, and the temperature rating will vary based on the gasket material you choose.
Inch fittings connect to another same-size fitting and squeeze the gasket in between for a tight seal.
304 stainless steel fittings have very good corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance.
3-A certified fittings comply with sanitary standards.
Note: To complete a connection, you’ll need two quick-clamp fittings, a clamp, and a gasket (all sold separately).
