NSPA’s new long neck ring terminals are IDEAL when using heat shrink tubing. The longer neck and 45° barrel design allows you to have a sealed termination without impeding the stud hole. The design also allows you to visually inspect that your wires are properly inserted before crimping.
As you can see with the two pictures below, the longer neck design (top) allows for variation of the tubing’s position and placement while still providing sufficient room for the recovered tubing to properly sealed and not impede the stud hole. Notice that the forty-five degree window allows you to see the stranded copper wire past the crimp area.
Standard terminal components were never designed to be used with heat shrink tubing and can often times block or obstruct the stud hole opening. This is illustrated in the picture below. The tubing is sealed but the tubing will likely impede a flush mount on a terminal block or screw.
This is a potential critical flaw when bare part terminals designed for PVC or Nylon are used with heat shrink tubing and stacking or mounting to a terminal block are required. In the picture below you can see the excess tubing needed to seal the area where the barrel’s throat meets the ring can prevent a flush mount to a block or when stacking terminals. This ultimately may result in less than optimal contact and potential connectivity issues. Notice how the tubing interferes with the stacked rings.
In contrast, NSPA’s new, long-neck terminals stack flush and without any impedance. Don’t risk electrical failure for your equipment and or vehicles. Ask your NSPA sales representative for information about our NEW long neck barrel rings and spades.
The biggest reason is to help prevent wire corrosion. Why is this so important? Well, because corrosion is a BIG problem. Did you know that in 2002 the U.S. Federal Highway Administration (FHWA) released the results of their two year study on corrosion and the finding were nothing less than startling.
† From their study… “Results of the study show that the total annual estimated direct cost of corrosion in the U.S. is a staggering $276 billion—approximately 3.1% of the nation’s Gross Domestic Product (GDP). It reveals that, although corrosion management has improved over the past several decades, the U.S. must ﬁnd more and better ways to encourage, support, and implement optimal corrosion control practices.”
The direct cost of corrosion in the transportation industry was estimated at $29.7 billion dollars per year. The breakdown was as follows:
- Motor vehicles – $23.4 billion – 79%
- Ships – $2.7 billion – 9%
- Aircraft – $2.2 billion – 7%
- HAZMAT transportation – $0.9 billion – 3%
- Railroad cars – $0.5 billion – 2%
Ugly corrosion can have a devastating effect on your electrical system.
Using a sealed, heat shrink connector is your best defense against the expensive damage corrosion can cause to your electrical system. Please visit http://www.nspa.com to learn more about our Sealed Electrical System and Heat Shrink Connectors.

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.
- 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.
- 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!
