BENEFITS / PROPERTIES
The bellows for the E-series is made from extruded PTFE by a patented process, They are certified for up to 100.000 cycles.
Main differences from the R-series are:
» Even more compact installation with no protruding from bolt ends.
» Greater lateral & angular misalignment due to the rigidity from the bolts.
» Unlike bolts the cables cannot be misadjusted unintended once installed.
» Cables cannot prevent torsion.
» Less strength than rods and require more often service.
» Installation can unintended be done with lateral misalignments beyond allowable limits.
Reinforced rings provide pressure strength for the bellow.
The PTFE bellow material provides excellent resistance for chemical and corrosion/aggressive
media at high temperatures. The smooth bellow surfaces make these bellows very suitable for
applications where CIP occurs.

Our PTFE expansion joints are available in circular shapes. They are by
principle builded similarly to Metal and Rubber types. They are for midrange pressures but high corrosivity resistance.
Our PTFE joints are certified for up to 100.000 cycles. (one cycle is defined
as neutral-compression-neutral – extension-neutral)
Our PTFE expansion joints can be useful for many industries, especially in
chemical, food & beverage industries, where high corrosion properties are
required.
Our PTFE Expansion Joints are designed and manufactured acc. to the
latest norms & standards.
The bellow is flared over the flanges, which eliminates the need for
separate gaskets. They offer low spring rates to protect sensitive
equipment
