Review on Valterra T01-0091VP Swivel Drain Connector - 90°, 1-1/2" x 3/4", Black - Efficient Plumbing Solution with Swivel Feature by Justin Boisvert

Good product that does what it is designed to do. However, the large nut/ring that attaches to the sink drain may have more threads. I found it easy to overtighten with my fingers, causing it to slip and damaging the plastic threads, making it even easier to overtighten. I repeat: tighten this product (with your fingers!) as LITTLE as possible to get a good seal and not damage the fine threads. I used it in my RV to attach a nice little stainless steel sink to my gray water tank. And another time at a cabin I used one as part of a drainage unit to turn a horse trough into a bathtub. Conclusion: buy. Be careful with that. It does the job.
