Described herein are corrugated heat protection tubes and methods of making the same. The heat protection tubes have improved heat resistance, improved abrasion resistance, and minimize or eliminate worker exposure to glass fiber insulating materials. The corrugated heat protection tubes can be used in automotive, transportation, and industrial applications, just to name a few.

Disclosed is a seal for an engine firewall. The seal including a proximal part having a recess; a distal part having a notch; and a flexible intermediate part integrally extending between the proximal part and the distal part.

A method and assembly for protecting a device connected to a wiring harness is disclosed. The assembly includes a protective tubular shield and a positioning device, with the protective tubular shield having a bore for receiving the device at least partially therein. An elongated wiring harness extends from the device being protected and through the bore of the protective tubular shield. The positioning device is formed having a band and at least one flexible, resilient finger extending radially inwardly from the band. At least one of the fingers forcibly engages the wiring harness to releasably maintain the positioning device and the protective tubular shield in a protection position along the wiring harness at least partially surrounding the device being protected.

Various systems and assemblies that can be utilized with hydraulic and other fluid flow lines are disclosed. According to one embodiment, the present application discloses an assembly that can include a first section, a second section and a third section. The first section can define a first passageway therein to receive and allow for passage of a fluid. The second section can define a second passageway that communicates with the first passageway. The second section and the first section together can form a first ball joint having an internal portion and an external portion. The first ball joint can comprise a moveable coupling between second section and the first section. The third section can define a third passageway that communicates with the second passageway. The third section can telescopically receive the second section therein and can be configured to form a linearly moveable joint between the third section and the second section.
