Agilent Fittings & Ferrules for HPLC
A range of high-quality fittings are available from Agilent, to ensure the ongoing security and performance of your LC equipment. It is important to utilize the correct fitting style and format, as specified by the manufacturer, to ensure accuracy and robust performance in every aspect of your apparatus, and Agilent create a wide range of fitting types to ensure that your system is covered.
For 1/16 in od capillaries, various stainless steel fittings are available, along with finger-tight PEEK fittings and PEEK RheFlex fittings. Other fittings provided include plastic, polyketone, bar removable and extra long fittings as well as replacement fittings and ferrules for capillary and nanoflow systems. An array of nuts, ferrules, various color identifiers and other supplies are also available for all fitting types.
Try InfinityLab Quick Connect fittings, the only truly finger-tight, reusable fitting for UHPLC. For harder to reach areas of the LC instrument, try InfinityLab Quick Turn fittings.
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
