- 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.
DIN EN 10357 fittings meet an international standard for butt-weld fitting specifications. This standard is common in the food and chemical industries.

Solder-Connect Fittings for Copper Tubing
- Temperature Range: 32° to 200° F
Solder these fittings to copper tubing or the tube end of another fitting for a permanent, leak-tight connection. They are also known as sweat fittings. Fittings have good corrosion resistance. To adhere to safety standards for drinking water systems, use fittings that meet NSF/ANSI 61 or EN 1057.
Copper tube size is the accepted designation of the copper tubing industry, not the actual tube OD.
- For Use With: Drinking Water
- Tubing: See table
- Specifications Met: See table
Fittings with center stop have a small internal ridge that prevents the tubing from sliding all the way through the fitting.
Fittings that meet ASTM B379 comply with international standards for tube fitting specifications.
