EPDM Rubber Flexible Connectors DIN4809
EMFLEX EPDM (
Ethylene Propylene Diene Monomer)
rubber flexible connectors are comprised of a synthetic
rubber membrane reinforced with a high tensile polyme
r
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.
Type RR Untied
EPDM rubber membrane reinforced with a nylon textile
cord and fitted with tied (oval) zinc plated carbon steel
flanges complete with isolating tie bars. Suitable for use on
hot water and chilled water under 10 bar. They are
approved to DIN4809 for use in heating plants and are
fully certified to this affect.
Type RR Tied
EPDM rubber membrane reinforced with a high tensile
cord and fitted with untied (circular) zinc plated carbon
steel flanges. Suitable for use on hot water and chilled
water under 4 bar unless the pipework is secured. They
are approved to DIN4809 for use in heating plants and
are fully certified to this affect.
