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.
304 stainless steel fittings have very good corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance.
Fittings that meet DIN standards adhere to international requirements for sanitary quick-clamp fittings. 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).

Butt-Weld Fittings for Stainless Steel Tubing
- For Use With: See table
- Temperature Range: See table
- Tubing:
304 Stainless Steel: Use with 304/304L stainless steel that meets ASTM A213, ASTM A269, or ASTM A270, except DIN EN 10357 fittings with only ASTM A269 or ASTM A270
316 Stainless Steel: Use with 316/316L stainless steel that meets ASTM A213, ASTM A269, or ASTM A270, except ASME BPE and DIN EN 10357 fittings with only ASTM A269 or ASTM A270 - Specifications Met: See table
Weld these fittings to tubing for a permanent, flush connection that permits smooth flow through a line.
304 stainless steel fittings have very good corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance.
DIN EN 10357 fittings meet an international standard for butt-weld fitting specifications. This standard is common in the food and chemical industries.

304 Stainless Steel Adapters, Caps, and Nuts: 3-A Certified 63-04
Gaskets: See table
Join these fittings with a threaded nut and a gasket for a secure connection that grants you easy access to your line. Also known as bevel seat fittings, the fittings are beveled to fit snugly around the gasket, creating a vibration-resistant seal. Fittings are polished to a smooth finish on the interior to prevent product buildup and bacterial growth.
316 stainless steel fittings have excellent corrosion resistance.
Note: For a complete connection, you’ll need a threaded straight adapter, an unthreaded straight adapter, a gasket, and a nut (all sold separately unless noted).
