Fiberglass Ferrules

External fiberglass ferrules are hollow tubes (T) cut from standard filament wound epoxy tubes (FWET). They are used to join two lengths of composite rods and tubes together to form longer fiberglass or carbon spars for kites, tents, and other products. All ferrules are named after the fiberglass tubes from which they are cut.

Internal Fiberglass Ferrules are either solid (S) or hollow filament wound epoxy tubes (T) and are inserted inside the ends of two tubes to connect them together. Internal ferrules make a smoother connection that does not have the bulk of an external ferrule. It is helpful to glue the ferrule into one tube.

The lengths of these ferrules may vary about +/- 1/2".

PLEASE NOTE: The FL-602 ferrules will only fit over .500" BLACK fiberglass rods due to the nominal outer diameter being a bit smaller than .500". In order to fit over a .500" WHITE fiberglass rod, the rod will need to be sanded down.
