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



- For Use With: Dairy, Water
- Temperature Range: -30° to 200° F
- Tubing:
304 Stainless Steel: Use with welded 304/304L or 316/316L stainless steel that meets ASTM A269 or ASTM A270
316 Stainless Steel: Use with welded 304/304 L or 316/316L stainless steel - Specifications Met: See table
Also known as I-line fittings, these fittings have a male adapter that interlocks with a female adapter for more support than standard quick-clamp fittings. They permit easy access to your line. With a smooth finish on the interior, they prevent bacterial growth and help you remove product residue. The pressure rating of the fitting will depend on the clamp you choose.
304 stainless steel fittings have very good corrosion resistance. They’re 3-A certified to meet sanitary design standards. 316 stainless steel fittings have excellent corrosion resistance.
On fittings with a butt-weld end connection, the flanged end of the male adapter interlocks with the flanged end of the female adapter to provide extra support to your line. To assemble, weld the adapters to tubing, then clamp the flanged ends together with a gasket for a strong, leak-tight seal that permits easy access to your line.
Fittings with a barbed end connection link flexible hose or tubing to your system. Secure with a hose clamp (sold separately).
Note: To complete a connection, you’ll need a male and female straight adapter, a clamp, and a gasket (all sold separately).

Clamps for Extra-Support High-Polish Metal Quick-Clamp Sanitary Tube Fittings
- Temperature Range: -30° to 200° F
- Tubing: Use with welded 304/304L or 316/316L stainless steel that meets ASTM A269 or ASTM A270
Connect extra-support quick-clamp fittings for a fast and easy way to access your line. Clamps have a wing nut that tightens by hand. They are 304 stainless steel for very good corrosion resistance.
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.
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).
