How to Identify and Measure Fittings

Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Temperature Range: See Gaskets

The smooth finish inside these fittings makes it easy to remove product residue. Also known as aseptic and tri-clamp fittings, they connect with a gasket, a clamp, and another quick-clamp fitting for a fast and easy way to access your line. The pressure rating of the fitting will vary depending on the clamp you choose, and the temperature rating will vary based on the gasket material you choose.

Inch fittings connect to another same-size fitting and squeeze the gasket in between for a tight seal.

304 stainless steel fittings have very good corrosion resistance. 316 stainless steel fittings have excellent corrosion resistance.

3-A certified fittings comply with sanitary standards.

Note: To complete a connection, you’ll need two quick-clamp fittings, a clamp, and a gasket (all sold separately).

Straight Adapters, Tube × Butt-Weld Tube

For Use With: Air, Beverage, Dairy, Food, Water
Tubing:
Inch Fittings: Use with welded 304/304L or 316/316L stainless steel that meets ASTM A269 or ASTM 270
Metric Fittings: Use with welded 304/304L or 316/316L stainless steel
Specifications Met: See table

Fittings with butt-weld end are also known as ferrules; they weld to tubing for a permanent, flush connection.

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.

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).

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.

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.

Straight Adapters, Tube × Barbed Hose

Fittings with barbed hose end connect to hose with a hose clamp (sold separately).
