2x3mm 1/20 14kt gold-filled crimp tube components, Size 2. Approximately 3mm long, 1.3mm inner diameter, 2mm outer diameter. Package contains approximately 119 pieces. Crimp tubes offer a secure and professional finish for many types of designs. These gold-filled crimp tubes do not fit the .024" Beadalon® when it's doubled. Also, when using these with 0.012" or smaller wire, the crimp should be flattened; the wire will slip out if crimping pliers are used to make the crimp round.
