BENEFITS / PROPERTIES
The bellows for the R-series is made from extruded PTFE by a patented process.
They can be supplied for over pressure and vacuum applications and are certified for up to
100.000 cycles.
Rods allow and control the movements at the same time, they also limit axial over extension and
misalignment and restrict/prevent harmful torsion to occurring to the joint. The rods are pre-set from
factory and must not be modified, which ensures the correct design conditions acc. specification.
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. For angular movements, please consult with us!

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
