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.
304/304L stainless steel fittings have very good corrosion resistance. 316/316L stainless steel fittings have excellent corrosion resistance.
ASME BPE fittings are polished to a 20 Ra finish for an extra-smooth interior that prevents product buildup and bacteria growth. Use them in pharmaceutical and bioprocessing applications.
