Idex VHP PK Fittings

Very High Pressure PK Fittings

Upchurch Scientific® Ultra High Performance fittings are manufactured from a proprietary PEEK™ blend (PK) which allow them to be used at higher temperatures (up to 200 °C) and higher pressures. The VHP PK One-Piece fittings are available for 10-32 coned, 6-32 coned or M4 coned ports, and Two-Piece fittings are available to connect either 1/16” or 1/32” OD tubing into 10-32 coned ports in multiple styles.



CAUTION: While the proprietary blend of the PK fittings will allow a fitting to attain a higher pressure and minimal cold flow properties relative to pure PEEK, some fittings molded of PK are known to be conductive. Use caution when employing PK fittings in high voltage applications.


MicroTight fittings and MicroFerrules:

While the MicroTight Female Nuts may be used with any of the separate MicroFerrules, the MicroFerrules themselves are port-specific and are thus not interchangeable. Additionally, the one-piece MicroTight fittings are also port-specific and should not be exchanged.
