VHP and UHPLC fittings The IDEX VHP (Very High Pressure) series is specifically developed for the extreme pressures found in modern HPLC and UHPLC systems. Where standard fittings reach their limit, the VHP line guarantees a leak-free connection for 1/16” or 1/32" tubing at pressures up to 30,000 psi (2,070 bar).

Innovative materials: PK polymer Many VHP fittings use PK (proprietary PEEK blend). This unique polymer combines the chemical resistance of PEEK with superior mechanical properties:
Minimal "cold flow": PK deforms less quickly under high pressure than pure PEEK.Temperature resistant: Safe to use up to 200 °C.Versatile: Used in FingerTight, LiteTouch® and MicroTight® designs for pressures between 12,000 and 16,500 psi.Part No. Description Port Pressure Rating Required Torque Head Style Material PK-100 VHP LiteTouch PK Ferrule for 1/16” OD Tubing 10-32 Coned 16,500 psi (1,140 bar) - - PK PK-110 VHP LiteTouch PK Nut for 1/16” OD Tubing 10-32 Coned 16,500 psi (1,140 bar) 8.0 in-lbs (0.90 N·m) Standard Knurl PK PK-132 VHP LiteTouch PK Ferrule for 1/32” OD Tubing 10-32 Coned 16,500 psi (1,140 bar) - - PK PK-120BLK VHP One-Piece PK Fitting for 1/16” OD Tubing 10-32 Coned 12,000 psi (827 bar) 8.0 in-lbs (0.90 N·m) Standard Knurl PK
