IP 300C buffer meets the requirements of the EN 15551 standard and the UIC 528 leaflet. The design of the IP 300C buffer meets all the conditions applicable to vehicles in operation. In IP 300C buffers, the energy is absorbed by expanding the buffer sleeve. Owing to the unique design, the buffer’s elastic area can continue functioning even after a collision. The buffer has good working parameters and operational reliability within the temperature range form -40oC to +50oC.
