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.
316 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.

Polished to a 20 Ra finish, these fittings have an extra-smooth interior that prevents product buildup and inhibits bacteria growth. Use them in pharmaceutical and bioprocessing applications. Also known as tri-clamp fittings, they connect with a clamp, a gasket, and another quick-clamp fitting for a fast and easy way to access your line. Fittings are 316 stainless steel for excellent corrosion resistance.
Fittings with butt-weld end are also known as ferrules; they weld to tubing for a permanent connection.
The pressure rating of the fitting will depend on the clamp you choose.
The temperature rating of the fitting will vary depending on the gasket material you choose.
Note: To complete a connection, you’ll need two quick-clamp fittings, a clamp, and a gasket (all sold separately).

Gaskets
Buna-N gaskets are oil resistant. EPDM gaskets resist water and steam and work well in humid environments. Silicone gaskets withstand high temperatures. Fluoroelastomer gaskets stand up to fuel, oil, and acid condensates. PTFE gaskets withstand harsh chemicals, with the exception of molten alkali metal and elemental fluorine.
