EPDM Rubber Flexible Connectors to DIN4809
Product Code: RR
EMFLEX EPDM (Ethylene Propylene Diene Monomer) rubber flexible connectors are comprised of a synthetic rubber membrane reinforced with a high tensile polymer textile cord. The collars are wire reinforced and the unit is complete with carbon steel flanges. They are capable of absorbing movement in several directions; axial compression, axial elongation and lateral deflection. A small amount of angular movement may also be allowed. They are normally installed in the pipework to isolate various items of plant which produce noise and vibration. These flexible connectors effectively dampen the transmission of sound and vibration from plant items in building services installations.

Vacuum support rings are available.
Working Pressure: 10 bar (1000 kPa)
Test Pressure: 1.5 x Working Pressure.
Working Temperature: -10ºC to 110ºC.
Key Features
Complies with DIN4809 Parts 1 & 2 and is fully approved and certified to this effect.
Verified burst pressure of 30 bar gauge minimum after 10 years service. An increased safety point.
Fully traceable and has the date of manufacture, DIN approval registration number, pressure and temperature rating, nominal diameter, manufacturer, type and identifiable colour coding permanently moulded into the membrane.
Laboratory tested for noise and vibration reduction capabilities.
Tied units are fitted with noise absorbing top hat washers.
Design Consideration
Rubber flexible connectors are subject to the same internal pressure force as metal expansion joints and the force is equal to the internal pressure multiplied by the maximum internal area. This force causes the connector to lengthen and tied units are recommended where the working pressure exceeds 4 bar, unless the pipework is secured to restrict movement.
Tie-rods are fitted through profiled flanges and to isolate the tierods from the flanges rubber top hat washers are used to prevent any metal to metal contact whatsoever, effectively preventing noise transmission.
After installation of TIED UNITS the tie-rod nuts should be checked to have 1mm clearance over the steel washers.
When using with plant items mounted on vibration isolators, such as springs or inertia bases, then TIED UNITS must be installed.
