Hey there! If you're connecting two pipes that aren't the same size, this PVC reducer fitting is exactly what you need. It's perfect for DIY plumbing jobs in bathrooms, kitchens, sinks, or even labs—anywhere you need a strong, reliable connection between different pipe sizes. Made from tough PVC, it's lightweight but seriously durable: weather-resistant, moisture-proof, and stands up to wear and chemicals. This one's a straight coupling style, so it's super simple to use. Just remember, you'll need some UPVC glue (not included) to secure it. Slather the glue on both the pipe and fitting, join them within a minute, let it set for 15, and wait a full 24 hours before using for the best hold. Quick heads-up: double-check your pipe sizes before ordering, because this fitting is specifically 3.5x3 inches. The bigger end measures about 4.15 inches OD, and the smaller end is around 3.51 inches OD. Oh, and it's not meant for standard ANSI or SCH pipes—just keep that in mind. Comes as a single grey reducer, ready for your next project!
