It was very simple to use and made our wire safe by providing a coating. We found using a heat gun helped it shrink to size. Review: Very impressed with this heat shrink insulation tubing! - I purchased the XHF UL Listed 1 Inch (25mm) 3:1 Waterproof Heat Shrink Tubing to be used on a submersible pump wire. I used it with a 14 gauge 3 conductor royal type wire. I had already sealed each wire connection (3) with waterproof heat shrink tubing with adhesive, but since the wire will be going in the water, I wanted to insulate all the connections and the wire itself, so I bought the 1" size of the XHF 3:1 waterproof heat shrink tubing so as to slide over all three waterproof connections. It concerned me that the XHF heat shrink tubing would not shrink enough to adhere to the 14 ga. wire itself.....but it did! The XHF heat shrink tubing did a marvelous job of shrinking around the three already insulated connections and then it shrank enough to adhere to the cable insulation itself, oozing out the glue on the ends to confirm it adhered! I am impressed! The XHF heat shrink tubing is not the normal thin heat shrink tubing you use for smaller wires, but is adequately thick too! I was impressed with the thickness and durability of this heat shrink tubing, even once it shrank. It was easy to use, as I just cut off the length I needed to cover the exposed 3 wire connections and and extra couple of inches on each end, to cover the cable itself. I then used a standard heat gun/paint stripper to heat the shrink tubing. It did as advertised.....shrunk enough to provide waterproof insulation with an adhesive. It didn't come with instructions, but if you heat from the center of the tubing (keeping the heat gun moving continuously) outward to each end, you should get the same satisfactory results as I got. I am pleased with this purchase and feel confident that it will provide the results (waterproof and durable) that I was looking for! Yes, I would purchase again! ## Features - [Better protection]: double wall heat shrink tube and lined with glue can better act on the wrapped objects. - [A wide range of applications] Shrink tube are mainly used for industrial, ship, wire links, anti-rust and anti-corrosion protection of solder joints, and audio and electrical DIY.

I used it to repair a carving knife handle that had been put in the dishwasher. The heat from the drying caused the handle to crack. The tubing is heavy enough and slip resistant to make a very quick repair. ## Frequently Bought Together - XHF 3/4 Inch (19mm) 3:1 Waterproof Heat Shrink Tubing Marine Grade Wire Cable Adhesive Lined Tube Insulation Seal Against Moisture Corrosion and Air Leakage, 4 Ft Black 1/0, 2/0, 3/0, 4/0 Wire - 1/2 Inch Heat Shrink Tubing - 10 Ft 3:1Ratio Waterproof Heat Shrink Tubin - Adhesive Lined,Dual Wall Adhesive Shrinkable Wire Wrap Tube - Black - XHF 20 FT 1" Heat Shrink Tubing Roll 2:1,Electrical Industrial Shrink Tube for Wire Insulation,UL Listed and RoHS Compliant Black --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.vu/products/80189412-ul-listed-3-4-inch-19mm-3-1-waterproof-heat](https://www.desertcart.vu/products/80189412-ul-listed-3-4-inch-19mm-3-1-waterproof-heat) --- *Product available on Desertcart Vanuatu* *Store origin: VU* *Last updated: 2026-05-03*
