316 Stainless Double Ferrule Socket Weld Connector, Tube × Socket Weld

The 316 Stainless Double Ferrule Socket Weld Connector, Tube × Socket Weld is an instrumentation tube fitting in 316L stainless steel, forged. Its tube end uses a nut with a front and a back ferrule that grip and seal on the outside of the tube; the manufacturer designs it to hold its seal through vibration, temperature swings and pressure cycling in instrument, sampling and control lines.

Construction

• Form: Socket Weld Connector, Tube × Socket Weld
• Ferrule system: double (front and back) ferrule
• End 1: tube end (nut and ferrules)
• End 2: socket weld
• Material: 316L stainless steel, forged
• Bar stock: ASTM A479, ASTM A276

Ends and sealing

• Tube end: a nut with a front and a back ferrule that grip and seal on the outside of the tube. Fit it to tube of the listed outside diameter; the pressure the joint holds depends on the tube wall.
• socket weld: socket weld end.

Sizes

6 part numbers, 1/8" to 1" tube. The Sizes & Part Numbers tab lists the size on each end and the Swagelok equivalent for every one.

• End 1: 1/8" tube to 1" tube
• End 2: 1/8" socket weld to 1" socket weld

Pressure rating

A tube fitting is rated to the tube it is made up on. The manufacturer publishes working pressures for 316 stainless tubing by outside diameter and wall thickness, from 2,000 psi to 12,000 psi (psi, by tube O.D. in inches and wall in inches):

Swagelok equivalents

For 6 of the 6 sizes the size table gives the Swagelok part number the manufacturer cross-references, so a part number taken off existing equipment can be matched to the Indus part number.

How to order

Quote the Indus part number from the size table. If you only have the fitting, send the thread or tube size on each end and the material, and Indus engineering will confirm the part number. Price and lead time are confirmed with the quotation.
