LASCO 03-4325 White Plastic Tubular 1-1/2-Inch by 12-Inch Slip Joint Extension with Nut and Washer

All tailpipes are the same, buy ombre a little longer than you need, just in case, cut off to correct length. Buy the cheapest one.

Ok I did not use this for plumbing I made a diy gravel vac for in between water changed. I bought cheese cloth bags for nut milks and attached it to the screw end. Drilled a hole about an inch above the bottom just big enough for an air stone and air line attached tubing to air stone and air pump. Bam beats the $60 Fluval all day. If you want to try this watch the KING of diy on YouTube. This made it even cheaper and permanent than if I had gone to Home Depot for the parts.

Does not include 1.25 inch washers which are needed for most drain installs

We installed a new vanity that was slightly taller than the previous one so the drain tailpiece did not reach the trap. This extension worked perfectly to get the two pieces connected again. I did have to cut it down a little bit since it was too long, but that was a 20 second job with a PVC cutter. Great product, and worked perfectly fine.

Basic pipe

The nut inside hole is bigger than some nuts I already had. The bevel washer is also thin on top. Both make the seal less of confidence builder.

The local stores were out. This was exactly what we needed.

Perfect fit. I repaired the under-sink job yesterday.
