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.
- Temperature Rating: Not Rated
- 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.
