How to Identify and Measure Fittings
Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

High-Polish Metal Quick-Clamp Sanitary Tube Fittings
- Temperature Range: See Gaskets or O-Rings
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 or O-ring, 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 or O-ring material you choose.
Inch fittings connect to another same-sized 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 or O-ring (all sold separately).

- For Use With: Air, Beverage, Dairy, Food, Water, except fittings with a 0.13" wall thickness cannot be used with dairy
- Tubing: Use with welded 304/304L or 316/316L stainless steel that meets ASTM A269 or ASTM 270
- Specifications Met: See table
Fittings with butt-weld end are also known as ferrules; they weld to tubing for a permanent, flush connection. Tank butt-weld fittings have an extra-thick wall for welding.

Clamps with wing nut tighten by hand. Clamps with bolt tighten with a wrench. They handle higher pressures than wing-nut clamps for a stronger, more secure hold.
