Agilent offers a comprehensive range of fitting varieties for Swagelok-type or metric M4/M3-type connections.

Depending on your application, different materials must be used:

 

  • Stainless steel or PEEK delivers permanent high-pressure sealing performance for connections such as valves, heaters, and columns
  • Stainless steel ensures permanent high-pressure sealing and optimal performance throughout your LC system up to 1200 bar
  • Finger-tight fittings (polymeric for 400 bar and polyketone for 600 bar) are a convenient option; they allow easy end fitting adjustment, so you can seat the capillary into the column properly, preventing extra-column voids and leaks
  • High-pressure fittings, which can be used with pressures up to 1200 bar, can be removed and replaced
  • It's a good idea to use stainless steel nuts and ferrules for instrument connections, and PEEK nuts and ferrules for column and guard column connections, since these are changed most frequently
Fitting type              Advantages / Tips
Swagelok-type fittings
  • Suitable for most connections
  • Available in a variety of combinations:
  • One piece or multiple pieces with nut + front and back ferrules
  • Stainless steel, PEEK, polyketone, or a stainless steel/PEEK combination
Metric M4/Metric M3
  • For micro valve connections
Stainless steel
  • At least 1200 bar
  • Most popular material for permanent, high-pressure sealing
  • Use our slitted socket wrench (Part No. 8710-2391) for optimal tightness
1200 bar removable fittings for 1290 Infinity LC
  • 1200 bar
  • Available in standard, long, and extra-long sizes for compatibility with columns that have different sized nuts
  • Removable and replaceable
  • Use our slotted socket wrench (Part No. 8710-2391) for optimal tightness
PEEK
  • Up to 400 bar (at ambient temperature with water)
  • Easy, finger-tight column connections
  • Ideal for frequently changed connections, such as column connections
  • Pressure is less critical
Polyketone
  • <600 bar (600 bar pressure rating)
  • Easy, finger-tight column connections
  • Fits stainless steel tubing
