It all comes down to the little connections that keep us running. A loose connection can come undone with vibration or a frayed wire being a fire hazard, it's the little connections we can't dismiss or skip replacing. Most of our partners have dedicated shelves and drawers containing our Würth connectors that serve several different needs. Whether it's for a high heat compartment or for a waterproof connection, our line of connectors covers applications across several industries. First, let's talk about:
Why you should choose Würth
Würth electrical connectors has been a "bread and butter" line of products at Wurth USA for decades. We research and innovate quality connectors that kept large machines running for many years. During our research, we've identified core differences between our products against the competition, and there's essential points you should be made aware of:
1. Longitudinal Shrinkage
Longitudinal shrinkage impacts insulation support and strain relief. Würth's tubing has the applicable wire gauges imprinted on the tubing for easy ID.
2. Diameter Shrinkage
Wall thickness and concentricity of tubing impacts dielectric strength (insulation support) and cut-through.
3. Not all Heat Shrink Connectors Are Equal
Würth connectors feature a sealed enclosure that provides an excellent waterproof shield while the competition has some exposted inner plating.
With these core features of our connectors, we ensure a snug and proper connection so your hard work doesn't come undone. Our sales teams are trained to demonstrate the strength of these connections so be sure to get in touch with your designated sales rep to see our different options of connectors in person!

What are OptiClear Connectors?
OptiClear Crimp/Seal connectors are designed to give the installer an optimal view of a crimp sealed connection. No more guess work - the installer will now be able to clearly see that a wire was stripped too short or that it has not been fully seated in the connector
By using this style of connector you get the following visual assurances:
Ensures the wire is crimped to the connector
Ensures the center of the crimp barrel is properly crimped
Clear waterproof insulation allows for indisputable inspection of the wire's condition

Parts of the OptiClear Connector
Window
Window in center of connector assures that wire is seated properly and the wire is being crimped to the connector.
Color-coded stripes identify wire gauge size to be used with connector
Color-coded stripes also guide the installer to the proper crimp position on the center of the crimp barrel.
Seamless crimp barrel butt connectors ensure superior crimp performance.
Wire-stop feature in the butt connectors prevents over-insertion of the wire.
ROHS compliant
45° Ring Terminal
45° Ring Terminal provides the same visual inspection as window butt connector
45° Ring angle of the barrel allows tubing to adhere to it & provides stronger seal
Longer ring assures a quality seal
Brazed seam barrel & serrations in barrel provide strong mechanical termination
Expanding product offering by 27 new terminals and connectors
Long Neck Design
Clear Tubing
Crystal tubing provides optimal clarity for visual inspection during installation & while in use
Provides a waterproof seal
Wire gauge imprinted on tubing
Military applications - can put in PM before deployment of equipment
What are Stepdown OptiClear Connectors
Our Stepdown OptiClear Connectors allow two different gauge sizes to be joined, all without the worry of a weak termination.
These connectors are designed to make it easier to crimp and provide a stronger crimp termination.
Others
This design is more difficult to crimp because the diameter of the butt connector is the same on both ends. Only the inside diameter is adjusted for the different wire gauge so the side for the smaller wire has a much thicker wall.
What are Nylon Insulated Connectors
Nylon Insulated Connectors are designed for heavy duty applications and superior performance for extreme vibration and moisture. Some of the core benefits are:
The tin plated annealed copper for improved corrosion resistance, max conductivity and crimp strength.
The barrel is serrated for a greater wire retention and pullout strength
Operating temperature range from -67°F to 221°F
UL/CSA listed where applicable
What are Vinyl Insulated Connectors
Polycarbonate (Makrolon) Insulated Crimp Cable Connectors
The inner part of the cable lug is made from high-quality electrolytic copper and electroplated with tin then soldered in the sleeve.
The dimensions comply with DIN standards
Halogen-free, self-extinguishing polycarbonate (Makrolon) is used as insulating material which has a superior heat resistant rating of up to 248°F. In contrast, PVC is heat rated to 167°F and both polyvinyl chloride and nylon are heat rated to 221°F
Excellent resistance properties against alcohols, mineral acids, gasoline, greases and oils
Excellent non-deformability properties - does not crack or create white stress points at crimp folds.
Parts of the Vinyl Insulated Connectors
What are Crimp/Seal Connectors
Features:
Translucent, adhesive-lined polyolefin tubing allows visual inspection, prevents corrosion and provides a waterproof seal
Conforms to automotive manufacturers' specifications for wiring repairs necessary for maintaining electrical warranties
Seamless butt connectors & brazed seam rings and spades prevent opening of connector barrel
Color-coded tubing with wire gauge imprint provides easy identification of the correct part for the job
Advantages:
Better wire contact with seamless barrels or brazed seams
Less voltage drop with a solid and secure crimp
Increased current flow with mechanically sound connections
Prevents wiring failures related to butted connectors
Decreases repair cost - reworks
Reduces equipment downtime
Superior tensile strength
Comparing with Competitors
Formed much like a butted seam, except the seam is brazed together with a silver alloy. May be used with solid wire and can be crimped on any side of the barrel without opening the seam.
Seamless connectors
Generally only available for a butt connector or splice. The barrel is created from one seamless piece of metal. This eliminates the problem of the barrel opening when crimped. May be used with solid wire.
Formed when metal is stamped, rolled and butted to create the connector barrel. Should only be used with stranded wire and must be crimped in the proper place to avoid opening the seam.
What are Solder/Seal Connectors
Features & Benefits:
Translucent, adhesive-lined polyolefin tubing allows visual inspection, prevents corrosion and provides a waterproof seal
Easy installation with pre-measured solder takes the guesswork out of the soldering process

How to use Crimp/Solder/Seal Connectors
What are Supreme Line Connectors
Features & Benefits of Supreme Line Connectors:
Lower melting temperature: New lead-free solder has a lower melting temperature: 280°F (138°C) vs 293°F (145°C).
Lead-Free Solder is Stronger: - Provided greater surface tension - Stays in place better, making it less likely to run out of the tubing - Provides greater tensile strength than other solder sleeves
No Hazardous Metals: - New solder sleeves are Tin & Bismuth alloy - Other solder sleeves contain both Lead & Cadmium - New solder - RoHS compliant - Better for the environment
New Ring Terminal Design: - 45° barrel allows installer to see wire is fully inserted and wire is crimped to terminal - 45° barrel ensures wire is stripped the proper length - Longer neck ensures a strong seal and allows multiple terminals to be stacked - Traditional ring terminals were not designed to be insulated with heat shrink tubing, which often results with the tubing impeding contact between the screw & terminal
