ACE TUBUS profile dampers are high-performance damping elements made of a special Co-Polyester elastomer. They constantly absorb energy even in difficult environments where other materials fail. Manufactured from one piece, they achieve long service lives. They are compact, lightweight, ready to install and inexpensive. Due to its solid construction and the harder Co-Polyester elastomer compound, the TR-HD family offers higher force and energy absorption with a shorter damping distance.
