Product description
The 316 Stainless Single Ferrule Bulkhead Union is an instrumentation tube fitting in 316L stainless steel, forged. Its tube end uses a nut with a single ferrule that grips and seals 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: Bulkhead Union
- Ferrule system: single ferrule
- Ends: 2 tube end (nut and ferrule)s
- Material: 316L stainless steel, forged
- Bar stock: ASTM A479, ASTM A276
Ends and sealing
- Tube end: a nut with a single ferrule that grips and seals 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.
Sizes
11 part numbers, 1/16" to 1/2" tube. The Sizes & Part Numbers tab lists the size for every one.
- End 1: 1/16" tube to 1/2" tube
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 |
