## Description

Wirefy 150 Wire Connectors - Wire Butt Connectors Heat Shrink - Heat Shrink Crimp Connector for Wiring - Electric Marine Grade Connector Waterproof Butt Splice Electrical Kit: desertcart.com: Industrial & Scientific

Review: Very Good Wire Connectors! - About six months ago I bought an assortment of Wirefy electrical connectors to re-wire an antique tractor for a customer. I had never used this brand of wire connectors, but found that they work well. I was impressed enough with Wirefy connectors that when I ran out of the 14-16 AWG Butt Connectors I ordered this refill. The connectors are of good quality, crimp easily, and the heat shrink tubing shrinks evenly and bonds to the wire insulation well. Again, I was impressed, and by-the-way, so was my customer! I'll be shopping Wirefy for my wire connector needs. (Note: This is not a paid endorsement, nor do I know anyone associated with Wirefy; they just make and sell good wire connectors!)
Review: Better than big box and cheaper too - Good option for cheap if you do a lot of splicing. Get the job done and better quality than standard garbage at home depot.

## Features

- Marine Grade Butt Connectors: Crafted from high quality tinned copper and adhesive lined heat shrink tubing. These professional butt connectors ensure protection against the elements.

Good option for cheap if you do a lot of splicing. Get the job done and better quality than standard garbage at home depot.

### ⭐⭐⭐⭐⭐ Reliable Seal and Great Value
*by B***J on December 9, 2025*

I’ve been using these connectors in a damp marine environment, and they’ve held up just as well as some of the higher-priced options I’ve tried. They crimp cleanly, the heat shrink tubing seals tightly, and I haven’t had any issues with moisture intrusion. I appreciate that each connection feels secure once heated, giving me confidence in long-term durability. For the price, the performance is excellent, and they’ve become my go-to choice for boat wiring projects. . What you may care about: • Seal quality (Meets) • Durability in damp environments (Meets) • Value for the price (Meets) • Ease of installation (Meets)
