STENFLEX

STENFLEX offers outstanding product quality in the field of flexible pipe connections around the world. Thanks to their special NBR lining, which is suitable for oil and oil-containing media as well as compressed air and coolant with added antifreeze protection, our STENFLEX expansion joints can easily be used in a wide variety of industrial applications such as control and drive systems.

STENFLEX products have proven their worth in the global market for over 50 years now. As an original equipment manufacturer of rubber and steel expansion joints, we supply all sectors, such as the machine construction, motor production and industrial equipment manufacture industries, whilst always taking into account all applicable standards such as the DIN, ANSI, JIS, BS, VG and SAE standards.

STENFLEX AS and RS expansion joints are often used for industrial applications in incredibly heat-intensive environments and are therefore tested for fire resistance in accordance with DIN EN ISO 15540/41. As part of this flame-resistance testing, the expansion joints are exposed to a temperature of 800°C with an internal pressure of 10 bar for a period of 30 minutes and must continue to function correctly during this time. Following flame impingement of the expansion joint, the joint must withstand a burst pressure test of at least 15 bar.
