NSPA Version

The barrel has two stripes – one on each end – to indicate where to crimp the connector. Plus, the stripe matches the crimp die that needs to be used. Easy to crimp & provides strong crimp termination!

  • Window for visual inspection
  • The inside AND the outside diameter of the connector is varied which means that both sides will make a sound mechanical crimp. 
  • Uniform copper wall – EASY to crimp

Competitors Version

The outside diameter of the butt connector is the same on both ends and only the inside diameter is adjusted for the different wire gauge. This means that the side for the smaller wire has a much thicker wall than normal and is extremely difficult to crimp. Almost impossible to crimp properly & wire can easily pull out!!

  • Thick copper wall – Difficult to crimp

Existing Problems with Traditional In-Line Connectors

  • In environments where corrosion and/or
    vibration are a problem, the closed-end
    connector can be used to replace wire nuts and other similar connectors.
  • Tubing has an active adhesive that seals multiple wires and eliminates wire pull-out

Existing Problems with Traditional Closed-End Connectors
