The pre-crimping function of the 3M Scotchlok UB2 branch connector simplifies processing and shortens processing time. Positioning and pre-crimping the wire in the connector prevents the wire from slipping out of the connector before the crimp is completed. A factory-applied sealant protects against moisture and corrosion. The UB2A connector enables uninterrupted branching of continuous wires. When the connector is used in branch joints, there is no need to cut double wires, open cables or test through the insulation. This branch connector is also available in a dry version, UB2A-D.
