Double lock coupling

It was always a problem to close the connection lines of an attachment:

When changing, here especially the dismantling of a hydraulic attachment, oil quickly runs out of the now open line after uncoupling.

Use this double lock coupling for all your hydraulic attachments. The lines are always cleanly closed even if only one side of the double lock coupling is still occupied. No oil leaks during transport and neither dirt nor unnecessary air get into the connection lines.
