The NTS Series Safety Breakaway Coupling from OPW represents the best available technology to protect your equipment, your people and the environment. Whether you are loading tank trucks, railcars, barges or ships, with liquid or gas; the NTS is designed to separate in the event of an unintended pull-away. Non-return valves positively shut both ends preventing spills and protecting the loading station at the same time.
