Abstract: A quick-set hydraulic coupler for use with the standard telescoping-type fluid or gas connectors on equipment within the agricultural, trucking, or tractor-trailer fields. The quick-set coupler includes a female half and a male half whereby the female half is mounted and includes a ring for engaging a lever. Depressing the lever will extend a spring biased inner member of the female half and expose a ring of retractable ball bearings that engage the male half. The lever is then released and the inner member retracts along with the coupled male member to form a tight seal.
