High-Polish Stainless Steel Tubing for Food, Beverage, and Dairy

The interior and exterior are polished to a high-luster finish to resist particle buildup and allow for easy cleaning. Tubing is welded with a smoothed weld bead on the inside.
304/304L stainless steel tubing has very good corrosion resistance. Tubing that meets DIN 11850 and DIN EN 10357 complies with international standards for food industry stainless steel tubing.
Note: Ra measures the smoothness of the tubing; the lower the Ra value, the smoother and more polished the surface.

- Compatible Tube Fittings: Butt Weld and High-Polish Quick Clamp
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.

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).

- 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.

Air Hose
Attach barbed fittings to this hose for use in low-pressure air applications. Hose has a smooth interior for unrestricted flow. It is reinforced with yarn for good strength. It won’t degrade when exposed to ozone or UV light.
Buna-N rubber hose has good abrasion and tear resistance.
