Method for Verifying Connection and Seal of a High Pressure Quick Connect

BACKGROUND

A typical brake tube assembly process uses a tube nut, flare, and port combination that, when run down

to a specified torque value, are likely secured and sealed. The current process of running down a brake

tube nut requires specialized tooling, and proper operator processing of the joint to ensure correct

assembly and sealing, all of which requires time to process correctly. Many systems throughout a vehicle

use quick connects that have various methods of mechanical verification that the connection and seal

were properly made, but there are few secondary checks that ensure proper connection that aren’t

dependent on a properly trained and attentive operator. This operator dependence has been one of the

main hurdles in implementing quick connects on a high pressure safety system such as the brake tubes

where partial connection may pass in-process checks but will not withstand the required operating

pressures.

METHOD

A method is proposed to remove the operator dependence in verification of a high pressure quick

connect, such as used in a hydraulic brake distribution system, through use of pressure verification of

the system by using pumps that are already available in the vehicle to generate maximum service

pressures post fluid fill but pre vehicle operation. Examples of these pumps for the brake system include

but are not limited to the electric brake booster...
