330PCS haisstronica Heat Shrink Butt Connectors-Marine Grade Waterproof Electrical Crimp Wire Connectors Kit-Tinned Red Copper Insulated, for Boat,Truck,Stereo,Joint(4Colors/4Sizes)

Works really good for my boat trailer, I live in Florida so it’s fully waterproof with the salt water here. Easy to wire I advise to use a heat gun or candle lighter don’t use a torch. Good product

Fantastic deal. Every garage needs butt connectors so look no further than these. They're well made and you'll have connectors for years to come.

Worked great! I like all the sizes

I use these often on auto audio and electrical. I like how they also have the heat shrink. Material seems of good quality thick and durable. Self explanatory so they are easy to use. I recommend this product.

Quality product, works as intended.

always good connections with these and they heatseal super tight . great price too.

Great quality. The heat shrink works great, and is waterproof if you make sure the wire jacket makes full contact.

Bought this to refill 2 kits I bought last year. They work great

Al principio creí que no funcionaba el plástico termoretráctil porque lo estaba intentando encoger con un encendedor. Normalmente el tubín termoretráctil(heat shrink) sí se encoge con un encededor común, pero este es más grueso, entonces al hacerlo con encendedor no funciona, no se encoge y se empieza a derretir y quemar antes de encogerse. Pero ahora que compré una pistola de calor, funciona excelente. :D

Il vaut mieux bien insister pour sertir sinon ça ne tient pas.

Took a moment to try this and really loved it. Very expensive retail but this set very reasonably priced, easy to use and comes in a convenient case. First time users should practice as I did. Heating the finished repair can be a bit tricky if you haven't done this before. Highly recommend.

très utile et bonne qualité
