540 PCS Heat Shrink Connectors

Very good set. Includes all fittings you could require. Particularly like the hook, meaning you don't have to remove nut completely, but still have firm fixing of ring. Recommended.

Reviews raved about these. Needed a good shrink fit connector but the wire hold through clamping is poor and the shrink fit surround is next to useless. These will burn or blacken before they shrink tight. Bought a large pack based on reviews as I have a significant marine project but these are only fit for the bin. Pay cheap buy twice! Serves me right!

Dopo aver provato tanti kit qui su Amazon, posso dire che questo è di gran lunga il migliore. La fattura è ottima, metallo grosso e generale sensazione di qualità. Ottimo anche il contenitore. Crimpati con una buona pinza sono di una resistenza alla trazione incredibile. Costano un bel pò, ma ne vale decisamente la pena. Francamente, non comprendo chi lascia una recensione negativa per questo prodotto. Da prendere ad occhi chiusi.

Facile à utiliser avec la bonne pince, le rendu final est top, digne des pros, surtout une bonne etanchéité avec le thermorétractable. Je recommande vraiment ce produit simple et efficace.

Ist ein gutes Set

A quality product. It has a dual wall plastic cover; the inner wall is glue and the outer wall shrinkable plastic. When heat is applied, the plastic shrinks (ratio 3:1) and the glue (polyolefin) melts to form a good seal. The best crimps are done with a ratcheting terminal crimper, which applies the correct pressure (see further below). There is a broad selection of crimps in the kit, both the type and the size (9 types in 3 sizes). A dual wall crimp saves space when that is scare, like on a boat or travelling remotely in a car. I take a selection of crimps in a smaller container to save even more space. The 540 piece kit has enough crimp terminals for most general purpose tasks around the boat or car. This is the best all round terminal kit I have purchased. There is a difference between a single wall and dual wall crimp, the glue in the dual wall gives a stiffer result with less movement, but it also improves the overall strength. If you an issue with vibration (like Outback Australia or Africa) a single wall crimp maybe better, as it reduces the damage caused by corrugations/vibrations by allowing more movement reducing the damaging effects of corrugations. Choose the best option for a given job. CRIMPING TIPS Some suggestions on getting good crimps: 1. Buy quality terminals like the Wirefy. 2. Purchase a good wire stripper like the IRWIN VISE-GRIP 2078300 Self-Adjusting Wire Stripper or the Klein Tools 11063W Katapult Wire Stripper. 3. Purchase a Ratcheting Terminal Crimper. If you want a variety of dye heads for different jobs look at the SG Tool Aid SGT18980 Ratcheting Terminal Crimping Kit. iwiss makes a range of specialist crimpers. 4. Strip the insulation from the wire to the correct length with the wire stripper (note how much quicker, easier and better quality the wire stripper is compared to a pair of pliers). 5. Match the Wirefy terminal to the wire thickness (important for good crimps). 6. Place the terminal in the correct dye in the crimping tool. I gently close the crimper to lock the dye onto the terminal but without compressing the terminal, then I insert the wire into the terminal and compress the crimping tool. 7. Using the correct size dye and placing the terminal correctly into the dye is important. 8. A ratcheting crimper applies the correct pressure to make a great crimp. 9. Use an electric/butane heat gun to shrink the plastic cover and melt the glue. I apply heat until I can see the crimp seal and a little glue comes out of the plastic cover. Wirefy terminals are translucent so you can see through the plastic to inspect the seal. 10. Let it cool. Job done. Test the crimp. 11. Common mistakes when crimping: a) not matching the wire size to the crimp terminal, b) not using the correct dye for a given terminal type, c) not correctly placing the crimp terminal correctly in the dye jaws. 12. Practice is important. Develop a good technique before using crimps in real life. I have cheap terminals and old wire and I practice to develop a good technique before doing a job for real. Test both single and dual wall terminals and see for yourself the differences in stiffness I discussed above. The initial cost of the tools can be expensive, but they will give you a life time of service. One job I did on my car, meant the tools paid for themselves. I wish I had brought them years ago! Buying the larger size kits like the 540 Wirefy saves money. I spilt the terminals between me and 2 friends – we all get a selection and a big cost saving. Buying terminals in small kits is very, very expensive. I have found more uses for the crimps than I originally thought.

Hele goed kwaliteit, maakt het na het krimpen mogenlijk om een waterdichte verbinding te maken. Perfect voor de automotive industrie.
