Rubber expansion joints

Amniflex rubber expansion joints are used in lots of applications that provide the compensation of thermal or mechanical movements. Bellows are made from various kinds of rubber, e.g. EPDM, Butyl, Nitril, Chloroprene, Viton and combinations.

Rubber expansion joints are often reinforced by steel wire cord, textile (rubberized) cord, nylon tire cord, PA textile cord etc. Therefore, they are capable to absorb axial, lateral and angular movements while being under low or higher pressures and temperatures. 

Due to the construction techniques and rubber quality and mixtures, rubber expansion joints are pre-eminently suitable for applications in water, warm water, drinking water, cooling water, wastewater, seawater etc. Our scope also covers the need of expansion joints for applications in (weak) acids, alkalis, compressed air, oils, gasoline, grease and solvents.

We also offer rubber expansion joints for oils, benzene, xylene, alcohols, esters, ketones, town-gas and natural gas and LPG (acc. to EN 589) and foodstuffs.

Amniflex rubber expansion joints can withstand temperature variations in a ranging from -25 °C up to 120°C (temporarily 150°C) and a maximum pressure of 16 bar.

They have an excellent chemical resistance as well as high physical strength. On top of it, rubber bellows have very good corrosion characteristics.

Amniflex rubber expansion joints are generally produced in sizes from nominal 20 mm (3/4”) up to nominal 1000 mm (40”) and with different flange types possible. If necessary, these flanges can be exchanged in our workshop. The expansion joints can also be supplied with tie rods, vacuum support ring and with PTFE lining.

For the Maritime as well as Industrial markets we also have Elaflex rubber expansion joints in our scope of supply. This top-quality German product has a wide range of type approvals ().
