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).
- For Use With: Air, Beverage, Dairy, Food, Water
- Tubing:
Inch Fittings: Use with welded 304/304L or 316/316L stainless steel that meets ASTM A269 or ASTM 270
Metric Fittings: Use with welded 304/304L or 316/316L stainless steel - Specifications Met: See table
Fittings with butt-weld end are also known as ferrules; they weld to tubing for a permanent, flush connection.

Nuts for Compression Fittings for Copper Tubing
Use these nuts with compression sleeves and fittings to create a strong seal on copper tubing. They are brass for good corrosion resistance.
Long nuts support more of the tube’s surface area than short nuts for a strong grip in high-vibration applications.
Nuts with a built-in sleeve (ferrule) help ensure the sleeve is positioned correctly for installation.
- For Use With: Air, Cutting Oil, Fuel Oil, Hydraulic Fluid, Mineral Oil, Water
- Temperature Range: -65° to 250° F, except metric fittings are -40° to 250° F
- Tubing: Use with copper
- Specifications Met: UL listed, except for metric fittings

- Specifications Met: FDA Compliant 21 CFR 177.2510, NSF/ANSI 51, NSF/ANSI 61, USP Class VI
Use these nuts with high-temperature compression fittings for food and beverage to create a seal on plastic tubing. They have a built-in sleeve (ferrule), so the sleeve is positioned correctly for installation. Thread the nut onto the fitting, then insert the tubing and tighten the nut. Nuts are PVDF (also known as Kynar), which has excellent strength and can handle high temperatures up to 270° F.
