We do have fittings though that reduce from this to 1/4." **Q: Can I use this for drilling a hole in a 5 gallon bucket to make my own water reservoir, or do i need another connector to attach to this on the bucket** A: This is all you should need - you unscrew the left half and it with the washer go inside the bucket, the right side on the right. **Q: Does it come with 1 or 2 adapters?** A: This is just the single bulk bulk-head fittings, if you buy our buckets which comes pre-drilled, those come with 2. **Q: What size drill bit should be used?** A: 1/2 inch, you could use a hole saw but I would prefer a unibit which can be found in the electrical section. It makes a much cleaner cut than the hole saw. ## Customer Reviews ### ⭐⭐⭐⭐⭐ It seals and flows. *by F***E on 12 December 2025* Does exactly what I expected it to do, air flow with a tight seal, I felt it was a little small at first, but I needed not worry, I used it for air flow though, so, I cannot give advice on flow rates on water with a pump or hydrostatic head. ### ⭐⭐⭐⭐⭐ As on the description. *by B***O on 28 September 2019* As on the description. ### ⭐⭐⭐⭐⭐ As advertising.... 8) *by Z***E on 6 June 2019* As described... 8) ## Frequently Bought Together - Blumat 30238 8mm Through-Hull Tank Connector, 8 mm - Blumat 32102 Shut-Off Valve for 8 mm Water Systems - Blumat Drip Feed Stroke 8 mm 10 m --- ## 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.za/products/55463041-8mm-through-hull-tank-connector-bulkhead-for-blumat-reservoir-rain](https://www.desertcart.co.za/products/55463041-8mm-through-hull-tank-connector-bulkhead-for-blumat-reservoir-rain) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-07-06*
