Coned fittings

IDEX coned port fittings are the most widely used connections in analytical instrumentation. These fittings use a conical port geometry, in which the ferrule seats in the cone of the port. This creates an extremely strong, leak-free seal that withstands the very high pressures of HPLC and UHPLC systems.

Whether you choose stainless steel or biocompatible PEEK, coned port fittings from IDEX Health & Science (formerly Upchurch Scientific) guarantee minimal dead volume and maximum reliability.

1. One-Piece Fittings (FingerTight)

The ultimate user-friendly solution. These fittings integrate the ferrule and the nut into a single part.

  • Benefit: Finger-tight up to 5,000 psi (350 bar).
  • Material: All-PEEK for 100% biocompatibility.

2. Two-Piece Fittings (nut + ferrule)

The traditional method combining a separate nut and ferrule for maximum flexibility.

  • Stainless steel options: For pressures up to 20,000+ psi in UHPLC systems.
  • PEEK options: Ideal for bio-analyses where metal-free paths are required.

3. VHP (Very High Pressure) Fittings

Specially developed for the latest generation of UHPLC instruments.

  • Performance: Tested at pressures above 25,000 psi (1,720 bar).
  • Innovation: Use of unique patented materials that do not "cold-weld" in the port.
