Popular one-piece fingertight fittings

The original One-Piece Fingertight Fitting was introduced almost 30 years ago and is still one of the most popular fittings offered by Biotech Fluidics for making liquid chromatography fluid path connections of 1/16 inch OD tubing to standard 10-32 coned ports in HPLC instruments. This PEEK fitting (F-120) can hold up to 345 bar (5000 psi) and is convenient and very easy to use since the only tool it requires are your fingers to tighten the fitting into the receiving port. It is available in colours of natural, blue, black, green, red, and yellow. This fitting also comes in a longer version (F-130) which can be more suitable for instrument designs with alternative layouts but requiring similar performance.

In addition, Biotech Fluidics offers a similarly designed Ultra High-Performance version of the One-Piece Fingertight Fitting. This is called VHP PK One-Piece fitting (PK-120BLK) and can withstand temperatures up to 200 °C and pressures up to 827 bar (12 000 psi) thanks to a proprietary PEEK polymer blend. Note that this material may be conductive to electricity and should thus be used with caution in high voltage applications.

Many of the fittings are available in packs of 10 pieces, as indicated by “x” at the end of the product number. Browse our online catalogue from IDEX Health & Science LLC for more information about fittings or contact Biotech Fluidics for guidance and to discuss your application needs.
