About
Product information

LFR is a flexible connection equipped with a pressed on Tri-clamp coupling. Pressing stainless steel 316(1.4571) ferrules onto the flexible connection makes the entire connection airtight and gives it a smooth flow profile.

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

The Tri-Clamp coupling is extremely simple to fit. Pressure-resistance and the correct assembly are guaranteed with the use of robust Tri-Clamps. This connection uses a seal which is available in many different materials. There is a possibility to supply tool release clamp rings.
