NEW… Crystal Clear Sealed Window Butt Connectors

Check out NSPA’s most recent line of Sealed Heat Shrink connectors… OptiSeal.

OptiSeal offers a unique crystal clear opportunity to visually inspect the integrity of your electrical system.

OptiSeal offers a unique crystal clear opportunity to visually inspect the integrity of your electrical system.

OptiSeal offers the following visual assurances:
• Ensures the wire is crimped to connector
• Ensures the center of crimp barrel is properly crimped
• Crystal Clear™ waterproof insulation allows for indisputable inspection of the wire’s condition

OptiSeal Components:

The Crimp Barrel:
• Window in center of connector assures that wire is seated properly and that the wire is being crimped to the connector
• Color-coded stripes identify wire gauge size to be used with connector
• Color-coded stripes also indicate/guide the installer to the proper crimp position on the
center of the barrel
• Seamless barrel butt connectors ensure superior crimp performance
• Wire-stop in butt connectors prevents over insertion of wire

The Adhesive-Lined Heat Shrink Tubing:
• Crystal Clear™ tubing provides optimal clarity for visual inspection
• Adhesive-Lined tubing ensures a waterproof seal
• Wire gauge imprint simplifies wire size identification

Solder vs Crimp connectors… which is a better solution?

Crimp versus Solder.  This age-old question goes back to our first caveman electricians.  Okay, maybe not that for back, but it is a question we hear ALL the time.  There really isn’t a definitive, one answer that fits everyone either.  We like to think of it as a user preference.  Here are some things to think about that will hopefully help you make your decision.

  1. Are you comfortable making a solder connection?  Often times, a “cold” solder joint can lead to electrical failure to do “pull-out”.  Installers must wait for the wire’s strands to heat up to promote good solder flow.  Typically, the bigger the wire, the longer the install time.  A good solder joint will allow the solder to flow in between your wire’s strands for maximum conductivity and strength.
  2. Do you have the right tool to crimp with?  Often times installers will try to crimp a terminal with the wrong tool.  This can damage the connector and can leave your connection at risk for failure.  Over-crimping a terminal can actually break the copper strands of your wires causing unintended resistance and less than optimal current flow.

Whether you choose to crimp or solder… or both… always use a weatherproof, heat shrink connector.  Do it Once, Do it Right!
