Review on 🔌 John Guest PP30121208WP Push-fit Reducing Tee: 3/8-Inch to 3/8-Inch to 1/4-Inch OD - Push-to-Connect by Tony Cole

Unfortunately I couldn't use this until the return window popped up. I used a lot of connectors to install our reverse osmosis system and run plumbing to two faucets and it had to fit in the fridge. Glad I checked before I hooked everything up - it leaked like a sieve at all three ends. I double checked my cuts were straight and burr free. Back then, the little zippers weren't inserted to remove the fitting, so I had to cut everything out and start over. I have purchased the Brass Shark brand for this app with somewhat more success.
