HPLC Fittings and Tubing for Chromatography Fluidic Connections
Explore HPLC fittings and tubing, including listed PEEK and stainless-steel components, and compare connection format, tubing dimensions, material, pressure rating and package quantity.
Selection Considerations
HPLC fittings and tubing connect components in the chromatographic flow path. Selection should start with the existing port and thread format, tubing outer and inner diameter, material compatibility and documented pressure requirements. Review the exact part number and system documentation before changing a fluidic connection.
- Confirm the port or thread format and match it with listed fitting and tubing outer-diameter requirements.
- Compare tubing inner diameter, material, length and stated pressure rating with the intended flow path and system conditions.
- Use the exact part number to review package quantity and avoid assuming that fittings, ferrules or tubing are included unless listed.

Frequently Asked Questions
What should be checked before selecting HPLC tubing?
Check listed tubing outer and inner diameter, material, length, pressure rating and the connection requirements of the existing system.
Are PEEK and stainless-steel fittings interchangeable?
Material and connection suitability depend on the method, solvent exposure, pressure requirement and hardware configuration. Compare the exact listed component with system documentation before installation.
Why is tubing inner diameter important?
Inner diameter influences the physical flow path and dead volume. Use the intended method and system configuration to determine the appropriate listed tubing dimensions.
