Slimsert Inserts/Fluid Fittings

Lightweight Inserts

Slimserts are lightweight, thinwall solid bushing inserts used by the aerospace and defence industries in a wide variety of applications including airframes, avionics and aero engines. 

Standard drills and taps are used for hole preparation, a simple swaging operation then locks them securely in place.

Fluid Boss Adapators

Lightweight Rosan Fluid Fittings are used in aircraft and racecar hydraulic systems. 

During installation a lock ring is used to secure it against rotation which gives the benefits of reduced weight and space plus the fact that only one wrench is needed to tighten the coupling nut - no more leaks due to inadvertently loosening the coupling.

Composite Fasteners

Tiodize have developed a range of composite fasteners that are similar in strength to aluminium fasteners but are lighter and in some cases have no radar signature making them suitable use in surveillance systems or x-ray scanners. Each fastener is designed to meet the individual requirements of the application and as such no standard range is available.

Bearings are also available in Tribo-Comp material that gives excellent lubricity and can be moulded into the housing for greater load carrying capability.
