Extra-High-Polish Metal Quick-Clamp Sanitary Tube Fittings

- For Use With: Air, Beverage, Dairy, Deionized Water, Food, Pharmaceuticals, Water
- Temperature Range: See Gaskets
- Tubing:
Fittings: Use with 316/316L stainless steel that meets ASTM A269 or ASTM A270
Gaskets: Use with 304/304L and 316/316L stainless steel - Specifications Met: See table
- Certification: Material Certificate with Traceable Lot Number and Test Report
Polished to a 20 Ra finish, these fittings have an extra-smooth interior that prevents product buildup and inhibits bacteria growth. Use them in pharmaceutical and bioprocessing applications. Also known as tri-clamp fittings, they connect with a clamp, a gasket, and another quick-clamp fitting for a fast and easy way to access your line. Fittings are 316 stainless steel for excellent corrosion resistance.
Fittings with barbed hose end connect flexible hose or tubing to your system. Secure with a hose clamp (sold separately).
The pressure rating of the fitting will depend on the clamp you choose.
The temperature rating of the fitting will vary depending on the gasket material you choose.
Note: To complete a connection, you’ll need two quick-clamp fittings, a clamp, and a gasket (all sold separately).

Hose Crimping Tool and Fitting Sets for Compressed Gas

Sets contain a crimping tool and a variety of fittings, nuts, and ferrules so you can connect pressure regulators, torches, and other components of your welding system. Fittings are also known as CGA (Compressed Gas Association) fittings. They are brass for good corrosion resistance.
Barbed adapters let you adapt to a threaded end so you can connect welding hose to pressure regulators or torches. They consist of a barbed shaft with a rounded end that sits inside a threaded nut so you can make a threaded hose connection.
Barbed connectors are also known as hose menders and splicers. Use them to connect lengths of hose or to repair damaged hose. Slide the barbed end into welding hose and use a hose ferrule and the crimping tool to secure the fitting to hose.
Threaded connectors let you attach threaded welding hose to pressure regulators and torches.
Fittings with left-hand threads are identified with a notch in the nut.
Note: Fittings have a CGA number that corresponds to a specific type of gas. Choose a fitting with the same CGA number as your tank and other system components.
