Every sealant gun has a clip/tab that YOU press to release pressure and cut off the caulk/sealant stream - NON-DRIP guns do this AUTOMATICALLY but they cost a bit more, BUT in the long term you will save money on spilled sealant and your finishing will improve. **Q: What is the Thrust Ratio of this gun** A: I dont know the exact answer but it's an amazing mastic gun I use it all day quite alot it's very good **Q: How do you get the cartridge into the gun ? The silver bar is solid to the end of the gun ? Is there a release button somewhere?** A: press the silver lever in at the back of the gun and pull the hook back while lever is depressed **Q: has this gun got a rotating barrel** A: Yes,I use this gun professionally, it is a very good tool ## Customer Reviews ### ⭐⭐⭐⭐⭐ Great quality and great price too. *by on Reviewed in the United Kingdom 31 March 2026* A good price and easy to use. Fast delivery and arrived safely and undamaged. This isn't one of them that only works perfectly once. Its a great product and great price too. Well worth getting this sealant gun. Glad that I bought it. ### ⭐⭐⭐⭐⭐ Best gun I’ve ever had *by on Reviewed in the United Kingdom 18 April 2026* Put this thing through its paces, used a lot and still going strong, would definitely recommend this gun ### ⭐⭐⭐⭐⭐ Excellent *by on Reviewed in the United Kingdom 22 January 2025* It's very good. Much more expensive than the cage variety, but then you get what you pay for. Delivers power to the cartridge with very little pressure, and solidly built (i.e. unlikely to bend and therefore become useless). Holds both sizes of cartridge as well. Get one, and you'll probably never need to buy one again. ## Frequently Bought Together - OX Pro Heavy Duty Sealant Gun 400ml - OX TOOLS P224301 Pro Heavy Duty Fixed Blade Folding Knife, Blue/Black - OX Pro 100 Pack Heavy Duty Knife Blades & Dispenser --- ## 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.pt/products/57043327-ox-pro-heavy-duty-sealant-gun-400ml](https://www.desertcart.pt/products/57043327-ox-pro-heavy-duty-sealant-gun-400ml) --- *Product available on Desertcart Portugal* *Store origin: PT* *Last updated: 2026-10-01*
