A fluid connector and lock combination is described for connecting a tube to a base element. A relatively fixed, threaded base element has a passageway for passing fluid. A threaded mounting connector for surrounding the circumference of a portion of a tube is provided and which also mounts the tube to the relatively fixed, threaded base element through threaded engagement. The connector maintains a seal between the tube and a corresponding surface in the base element when the connector is sufficiently threaded to a sealed position relative to the base element to prevent leakage of fluid across the seal. A linkage is provided between the connector and the base element for preventing unthreading of the connector from the sealed position relative to the base element. The linkage includes a first portion which is linked to the connector and a second portion which engages slidingly in an axial direction the base element for preventing relative rotation between the connector and the base element.

Hydraulic fitting locks

A fluid connector fitting nut lock includes a sleeve that fits down over the nut and that has an integral locking mechanism to fix the sleeve in a raised position that allows the nut to be turned and in a locked position that prevents the nut from backing off due to vibration or other external forces. The integral locking mechanism eliminates the need for a separate lockwire or clipwire.

Hydraulic fitting nut lock

A fluid connection is formed between a tube for carrying fluid and a parent material having a surface wherein the fluid passes between the tube and the parent material. The connection has a first wall in the parent material defining a flow passage having a first diameter in the parent material for the fluid. A second wall is formed between the first wall and the surface of the parent material. Threads are formed in the parent material between the second wall and the surface of the parent material for engaging an insert. A tube having an end portion placed adjacent the second wall is used in the joint wherein the tube is sealed in the parent material between the first wall and the threads in the parent material. An insert engages the threads for maintaining the tube in a sealed condition.

Hydraulic connector

A barrel nut fastener apparatus that includes a nut loosely retained in a prescribed position by a retainer that is adapted to be slidably received in a cylindrical bore formed in a panel. The nut is carried loosely on a seat formed in the retainer and is positioned to threadedly receive a bolt projecting through aligned transverse holes in both the panel and the retainer. The nut and seat have conforming cross-shaped configurations such that the compressive force of their engagement is distributed over a relatively large area, thereby substantially reducing the possibility of the nut being deformed if the bolt is overtightened.
