STAINLESS STEEL / TEFLON CONNECTION KIT

The tips and tricks in this section are related to the Fluidic Connect in combination with the

Stainless Steel or Teflon Connection Kit.

I connected all components according to the manual, but the connections still leak. What can be wrong?

1. Make sure the connections are finger tight (see 5.1. Tightening Force), if so DO NOT

tighten the connections any further, it might break the chip.

2. Check if there is no tension on the tubing, causing the tubing to exert a force on the seal.

3. If the tubing exceeds the ferrule edge, this can cause the problem, see figure 5.2.
