Flangeless Fitting System Connection Guide

The Flangeless Fittings system is designed to connect tubing into any appropriately-threaded flat-bottom receiving port.

To use properly, follow these instructions:

1. If you are using polymer tubing, cut the end of the tubing, leaving a square-cut face; if you are using stainless steel or other metallic tubing, simply ensure the end of the tubing is flat and burr-free.
2. Slide the Flangeless nut over the tubing, with the nut threads facing the tubing end being connected.
3. Slip the Flangeless ferrule over the tubing, with the tapered portion of the ferrule facing towards the nut.
4. Insert the tubing with the ferrule in place into the receiving port, and, while holding the tubing down firmly into the port, tighten the nut finger tight.
