What is it made from?

316L stainless steel, forged. The manufacturer states the material on every part in this family.

Which sizes are available?

26 part numbers, 1/16" to 1" tube. The Sizes & Part Numbers tab gives the size on each end for each one. Sizes outside the table are quoted on request.

What pressure is it rated to?

The manufacturer publishes tubing ratings from 2,000 to 12,000 psi; the table on this page gives the figure for each size and tube wall. Treat them as the manufacturer's figures, not a guaranteed minimum.

Tube end: a nut with a front and a back ferrule that grip and seal on the outside of the tube; NPT: taper pipe thread that seals on the thread flanks, with sealant or tape.

Product description

The 316 Stainless Double Ferrule Female Connector, Tube × NPT Female 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: Female Connector, Tube × NPT Female
Ferrule system: double (front and back) ferrule
End 1: tube end (nut and ferrules)
End 2: NPT female
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.
NPT: taper pipe thread that seals on the thread flanks, with sealant or tape; ASME B1.20.1.

Sizes

26 part numbers, 1/16" to 1" tube. The Sizes & Part Numbers tab lists the size on each end for every one.

End 1: 1/16" tube to 1" tube
End 2: 1/16" NPT (1/16-27) to 1" NPT (1-11.5)

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):

Tube O.D. (in) \ wall (in)	0.010	0.012	0.014	0.016	0.020	0.028	0.035	0.049	0.065	0.083	0.095	0.109	0.120
1/16	5600	6800	8100	9400	12000
1/8						8500	10900
3/16						5400	7000	10200
1/4						4000	5100	7500	10200
5/16							4000	5800	8000
