Collars are specific metal connections that are applied to join two pieces of a hose, to close up a hose or to create a base for further fittings. Crimp collars require radial crimping to get properly attached to a hose. The principle of crimp joints is simple - the shape of the fitting is altered by applying mechanical force, and thus it is permanently linked to a hose. Such connections require special devices to apply gradual pressure to the joint in order not to deform it in an undesired way. Crimp collars create a strong permanent bond that is very hard to separate or break. We offer a range of such items for the lowest prices available. Shop for the best with MegaDepot.
