The SEB gas hydraulic buffer series provides a premium robust solution for medium speed applications.
A self contained, maintenance free* unit designed to weigh approximately half of a conventional buffer and have a small space envelope. This means that shipping costs are significantly reduced and allows for quick and easy installation.
The SEB series is designed and built according to strict engineering standards and is universally approved and globally certified.
