The FDM is a flexible connector that has metal flanges pressed onto the material. A loose gasket seal is then added, making the connection airtight and giving it a smooth flow profile. The flanges are available in stainless steel 304 (1.4301) and stainless steel 316 (1.4571).

FDM
FDM is a flexible connection equipped with a pressed on Jacob coupling.
The Jacob coupling is assembled in the same way originally intended, with a replaceable gasket and a Quick Connect Clamp for quick assembly.
It can also be used with a Bolt Connect clamp for Employee safety in case of dangerous applications, for instance when the flexible connections is close to a rotary valve, screw conveyor, butterfly valve, mill or other mechanical equipment.
The FDM flexible soft connections is a great addition to the already vast program of the modular Jacob tubing system.
The design of the method the flexible soft sleeve is pressed on to, the Jacob Flanges allows us to make the flexible sleeve in a great variety of materials, thermoplastics, rubbers and silicones. In thicknesses, 0.3mm, 1.0mm, 2.0mm, and even 3.0mm thickness.
The use of a U shaped Gasket ring on the flange, which is replaceable, allows you to choose from a wide range of gasket materials for a variety of applications and even metal detectable gaskets.
Pressing stainless steel Jacob flanges on to the flexible connection / flexible sleeve, 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, color and metal detection.
Magnets, sensors and switches
Also the flanges pressed on to the flexible, allow to weld brackets mount electromagnets, sensors or proximity switches. This for the safety purpose to detect if there is a flexible mounted.
Also when the clamp is disassembled, electromagnets can keep the flexible in place to prevent leaks or to guard operators from mechanical moving parts that are dangerous.
Machines can be switched of when the right electronic precautions are made.
Also ground studs / earth studs can be added to the metal press rings on each end.
