Full saltwater proof on boat trailer
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

A lot cheaper than buying a small package from the parts store.
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.

Good quality connectors
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.

Good product, poor packaging
I recently did a couple of automotive rewiring projects and needed bulk heat shrink connectors in different sizes. This set was inexpensive for the amount you get and they worked great, providing a nice, neat, seemingly solid wire junction with just a little heat application from a heat gun. Only removing a star because the plastic box they come in is super flimsy and the lid broke off almost immediately. You will want a better container to store them in.

Keeps water out
Work great! Glue oozes out to form a weather tight seal. Make sure to use crimpers with flat jaws so the plastic insulation isn't pierced on the butt connector. Jaws with pointy teeth will pierce the plastic insulation and let water in.

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

Marine Grade Heat Shrink
Great product for the price. Would order again.

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.
