Tube End Caps

The two end-cap parts have some reference pins which are housed in special counter-seats. Two cavities inside the end-cap are provided for housing two hexagonal nuts DIN 934. Thanks to the tapered shape of the cavity, the end-cap exerts a pressure on the inner walls of the tube, due to the tightening of the nuts, thus ensuring the tensile strength of the connection. The level of the tensile strength depends on the tube dimensional tolerances, the condition of the tube inner surfaces and the tightening torque applied. The end-cap enables the joining of round tubes with other elements or the installation of wheels or levelling elements with locking nut. The installation of a simple levelling element does not enable the expansion of the end-cap: for this kind of applications the use of NDL.T end-caps is a more proper alternative. The assembly can be performed simply by positioning the end-cap inside the tube, with no need of screws or other fasteners.
