Measure your pipe and fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.
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.
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 Gasket Fittings for Stainless Steel Tubing
- For Use With: Air, Dairy, Water
- Temperature Range: See Gaskets
- Tubing:
Inch Butt-Weld Fittings and Quick-Clamp Fittings: Use with welded 304/304L or 316/316L stainless steel that meets ASTM 269 or ASTM 27
Metric Butt-Weld Fittings: Use with welded or seamless 316 stainless steel - Specifications Met:
304 Stainless Steel Adapters, Caps, and Nuts: 3-A Certified 63-04
Gaskets: See table
Join these fittings with a threaded nut and a gasket for a secure connection that grants you easy access to your line. Also known as bevel seat fittings, the fittings are beveled to fit snugly around the gasket, creating a vibration-resistant seal. Fittings are polished to a smooth finish on the interior to prevent product buildup and bacterial growth.
316 stainless steel fittings have excellent corrosion resistance.
Note: For a complete connection, you’ll need a threaded straight adapter, an unthreaded straight adapter, a gasket, and a nut (all sold separately unless noted).
