Looked for youtube videos - no luck!** A: The fitting itself is watertight. If its not, its defective. Once you push the pipe into this fitting you will feel it "pop" or "slip" into the seat where it becomes watertight. If its sitting right, you should not be able to pull this pipe out, nor should there be any leakage from it. **Q: Can you control the speed of water flow through this valve?** A: I don't see why not. For my use, it's only open or closed. You would actually be controlling the amount of flow not the speed. **Q: Does this value have or require a california proposition 65 warning for california residents? thanks!** A: Prop65 applies to any material, the warning is required even if a trace amount of over 1000 substances from the Prop65 list maybe present. We have the warning on our bags to comply with the requirement of the Prop65 regulation for “clear and reasonable” warning. **Q: Does this work with 1/4 in drip irrigation tubing?** A: I used it with a 1/4" pex line for a fridge filter not totally sure about the irrigation line, you can try it out for a test before installing to be sure. A good sharp tubing cutter will help for a better seal and fit. Good Luck ## Customer Reviews ### ⭐⭐⭐⭐⭐ DIY Plumbing Success: Easy Fridge Water Supply Fix 🚰👍 *by C***N on Reviewed in the United States on 28 January 2024* TLDR: 🌟🌟🌟🌟🌟 Effortlessly installed a shut-off valve for my fridge's water supply, saving time and money without needing a plumber.I recently faced the challenge of moving my fridge, but the lack of a shut-off valve for the copper water tubing meant potentially turning off the house's water supply, which wasn't an option. To tackle this, I armed myself with a pipe cutter, a handy gadget, and a hopeful spirit.The installation process turned out to be surprisingly simple. The first end of the gadget connected with a reassuring "pop," signaling a secure fit. The other end was a bit more stubborn, not clicking into place right away. Sensing something amiss, I applied pressure to both ends simultaneously, and sure enough, the second "pop" confirmed a successful connection.When I turned the house's water back on and switched the new valve to the 'on' position, water flowed smoothly with no signs of leakage. The feeling of triumph was immense! This quick, five-minute fix cost just a fraction of what hiring a plumber would have, with the toughest part being just moving the fridge.This DIY solution proved to be a highly effective, quick, and cost-efficient way to add a necessary shut-off valve, enhancing the practicality of my kitchen setup. ### ⭐⭐⭐⭐⭐ Costoso ma funzionante *by G***I on Reviewed in Italy on 7 January 2024* Pensavo costasse meno ma è esattamente quello che mi serviva al lavoro.Un ottimo prodotto resistente. ### ⭐⭐⭐⭐⭐ Both ends 3/8 shut off valve *by J***R on Reviewed in Canada on 10 August 2020* Work great and easy to use ## Frequently Bought Together - John Guest Speedfit 1/4 Inch Shut Off Valve, Push to Connect Plastic Plumbing Fitting, PPSV040808WP - John Guest Speedfit 1/4 Inch Union Tee Connector, Push to Connect Plastic Plumbing Fitting, PP0208WP - John Guest 1/4 Inch x 25 Feet LLDPE Tubing, Flexible Water Tubing for Plumbing, Natural, PE-08-BI-025F-N --- ## 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.tn/products/340302020-john-guest-jg-speedfit-ppsv040808wp-1-4-inch-by-1](https://www.desertcart.tn/products/340302020-john-guest-jg-speedfit-ppsv040808wp-1-4-inch-by-1) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-08-17*
