CFL is a flexible connection equiped conical lipped bolted on Tri-Clamp flanges.

The triclamp flange is machined from a single billet. The Triclamp adapter has a conical machined lip on which a straight flexibles sleeve slides on. A counter conical counter flanges is than bolted on with a machined in gasket ring, to seal the sleeve against the conical lip. This construction means that a flexible sleeve can be cut from a roll at length and be mounted between these flanges.

The standard tri-clamp gasket is replaceable, as well are the gaskets that seal the adapter flange to the flexible connector. For both gaskets there is a choice out of a wide range of gasket materials. All the metal parts can be re-used when the flexible sleeve is replaced. This is a great advantage. By using the standard couplings on the market, you can use a wide variety of connection clamps. For example, the standard tri-clamp accessories or the versions which allow for tool release or a padlock for instance.

Brackets or braces can be placed or can be incorporated in the design to fit magnets, switches or contacts. Also, other electronic devices that either detect the presence of a flexible connection or keep it in place such as electromagnets can do, even when the clamps are removed. It can also be made suitable for lock out tag out (LOTO). This can all be of importance when the Flexible Connection is close to a rotary valve, screw conveyor, butterfly valve, mill, any other mechanical equipment or when a harmful gas is present inside the tubing.

The CFL is designed to create a connection free of any hollow bodies and without any lip or edge that would be hard to clean or could entrap contaminations or product. Not only Triclamp is an option, but all sorts of quick action type of flanges. Because of the rigid metal adapter parts making it vacuum and over pressure resistant at the same time. As well as fully customizable to your demands.

There are many application options, including specific options for weighing and dosing techniques, ATEX, foodstuffs, chemical and color and metal detection.
