Using this product our team found that it was incredibly easy to apply the shrink tubing to our electrical connections. The tubing shrinks evenly and smoothly when applied with a heat gun, creating a tight seal around the wires .The TUBING is also quite durable and doesn't tear or break easily during installation. The only downside is that it can take a bit of practice to get the heat gun temperature just right to avoid burning the tubing. Overall, we highly recommend this shrink tubing for any
