Review on Uxcell Extension Stainless Fitting Coupler by Tone Hatton

This extension (50mm) is almost perfect for what I used it for (between filter and rod holder) except the internal thread at the end is twice as long as I needed . This would be ideal for a pipe coming out of a wall. I had to use both a washer and 4-5 turns of tape to get a waterproof fit as the threads are REALLY DEEP. But it works, it's all metal, and apart from the deep threads and the very long internal thread, it works well (I couldn't find this product at my local hardware store, so you know). If the female threaded part wasn't a full third of the length of the extension (again I got 50mm) it would be 5 stars.
