Low Pressure Threadless Connector

When Europower Hydraulics ceased trading in 2011 Fluid Power Design Solutions purchased the designs and associated tooling for their Low Pressure Threadless Connector which at that time was, and continues to be used by global OEMS including: Volvo, Case New Holland, Scania Trucks and AGCO Group.

This product has been in service continuous for over 18 years with over 5 million individual connectors in use. To date there have been zero accidental disconnections and zero reported leakages or warranty claims.

How long does it take to correctly assemble threaded connectors with a spanner? With the Low Pressure Threadless Connector it takes as little as 3 seconds as can be seen in the video below:
