First off, all the parts are included-nothing missing. Next up, everything for including the seals. Excellent product at a fair price. ### ⭐⭐⭐⭐⭐ Great product and inexpensive *by R***. on July 13, 2025* These are actually pretty handy and inexpensive for what they are. They come with everything you need. I don’t use the terminal block that comes with it but I’m sure it’s fine. ### ⭐⭐⭐⭐ Cheap, but not too cheap. Supply your own terminal strip though (replace what it comes with) *by D***N on October 16, 2025* The busbar screw terminal thing it comes with is cheap, and the lid does have a gasket but it's thin. It does come with multiple glands for larger wire sizes, but not anything thinner than 18AWG (and that's still pushing it). HOWEVER, this gets high marks because I used it to splice in tail lights on a car hitch lift, and it has survived driving through deep puddles at speed (not submerged), heavy downpours, and being out in the Florida heat. I haven't had this for a full summer season, and this will be the first winter in the North. I took the extra precaution of RTV silicone over the wires at the glands, some wire loom tape over the outside connectors, and dielectric grease over the terminal strip that I supplied myself. We'll see how it does long term. ## Frequently Bought Together - Helunsi 2 Pcs Waterproof Junction Box 3 Way, IP68 External Waterproof Electrical Junction Box, Black Underground Junction Box Outdoor Cable Connector, for Diameter 5mm -14mm Wire Gland (Larger) - Tynoscco IP68 Waterproof Junction Box Outdoor,4-Way Electrical Junction Box Outdoor with 4 Cable M25 Gland Wire Connector Extension Electrical Cable Protector for Diameter Cable Ø4-14mm Black - Junction Box Outdoor 2 Way Waterproof IP68 Electrical Cable Connector,M16 Wire Range(3.5-10mm),Suitable for Repair and Extend Power Cables,UL(5 Pack) --- ## 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.co.th/products/171614665-helunsi-2-pcs-3-way-waterproof-junction-box-ip68-electrical](https://www.desertcart.co.th/products/171614665-helunsi-2-pcs-3-way-waterproof-junction-box-ip68-electrical) --- *Product available on Desertcart Thailand* *Store origin: TH* *Last updated: 2026-09-01*
