Dr. Watson - Mouthpiece Stem Replacement for Tobacco Pipe, Bent, fits 9mm Filter

I am very pleased with this purchase. I have the tendency to keep my pipe in my mouth throughout the day clenched between my teeth. This stem is durable compared to other cheap plastic stems that usually crack and break.

Loose fit for my standard 9MM pipe (had to put a wrap of aluminum tape on it, then it fit). Mouthpiece is also thicker than a standard pipe stem (a little uncomfortable). It does accept a 9MM filter.

The insert is way too big for a standard pipe, and the material feels very cheap for the price. Not even sure what pipe this would fit into, let alone the filters that would work. I would not recommend buying this item.

There is no drilled hole on this stem. It is wide open inside which causes too much airflow and overheating of pipe. Stem has empty air chamber inside.

OD of tenon is too big. 9mm filters are like a hot dog in a hallway. Thought it was just going to be a snug fit and forced it, cracking my pipe. Oh well, that is why I got a cheap pipe. You live, you learn, you rate...

This squeezed the Vauen filter to the point where it closed the mouth (blue) end and smashed the heat end.

Fell apart after about one month of occasional use. Total junk...don’t buy.

It was too big for my pipe I'm very disappointed
