Our tip: PTFEGlossaryPTFEPolytetrafluoroethylene tubing is ideal for the “normal” work in laboratories.
If you need tubing which is absolutely gastight even in limit range of pressure and temperature, you should choose PFAGlossaryPFA Perfluoroalkoxy or FEPGlossaryFEPTetraflouroethylene-Perflouropropylene. PFAGlossaryPFA Perfluoroalkoxy only has advantages at temperatures of more than +205°C, but is more expensive than FEPGlossaryFEPTetraflouroethylene-Perflouropropylene tubing.
Depending on the tubing dimensions – for details please look at our price-list. Minimum lengths are unfortunately necessary for granting a low price per metre.
Free choice of requested length between minimum length and maximum production length
For tubing up to O.D. 10 mm, quantities of up to 100 metres in one length are possible without extra charge; quantities of more than 100 metres in one length are only available in particular cases – please ask us.
If our inventory or the ordered quantity does not allow another possibility, the tubing is supplied in partial lengths without consultation.
Example: 90 m, 57 m, 23 m
Tubing up to an O.D. of 3 mm and with a minimum length of 30 m is supplied on reels. This prevents bends and twists and makes storage and rolling up easier.
Several rolls with the same lengths are available at low extra charges, e.g. 5 rolls of 40 metres or 11 rolls of 22 metres.
Stricter tolerances than the general industrial standard GKV – perfect interaction with our BOLA Fittings and BOLA Stopcocks.
When choosing the wall thickness, a couple of issues have to be considered:
Practice has proved that tubing varies in diameter. We therefore recommend to check before assembly whether the tubing outer diameter corresponds to the nominal size (e. g. Ø 6 mm). The values in the right chart will be helpful.
The surface of PTFEGlossaryPTFEPolytetrafluoroethylene tubing can be damaged if V-rings are inserted by force and result in leakage.
