A tuning cable for hydraulic system noise reduction is secured to a secondary fitting where the secondary fitting is mounted in a primary fitting using a pressed-in fit, a threaded connection or a slip fit after a tuning cable is installed in the secondary fitting by crimping the secondary fitting. The primary fitting is secured to a hydraulic connector which is also secured to a hydraulic hose to form a hydraulic hose assembly. In an alternative embodiment the secondary fitting is slipped directly into the hydraulic connector.

Fitting system for a hydraulic tuning cable

A connector having a tuning tube attached to a secondary fitting where said secondary fitting is secured to said connector using a press fit or a mating thread structure and where said tuning tube is pinched between two different bore radius sections within the connector and a sleeve section of the secondary fitting. In an alternate embodiment, the tuning tube is held by one or more barbs or sharp edged annular rings formed on the inside bore of the connector. The tuning tube can be made of one or more sections of tubing joined together.
