the edge? There's nought to grab on to, and I don't want to injure the threads on the original fixture. The brass is giving of soft, just not soft adequate to pull out beside needle proboscis pliars, I sprayed WD-40 and tried to rotate it, but I can't. It's an expensive piece of bathtub faucet and I don't know what to do?

Answers:    There is a wrench you can get hold of that grips the pipe from the inside.

In plumbing, a nipple wrench is often certain as an inside pipe wrench.

An eccentric toothed gear is mounted on a hexagonal shaft. The wrench is introduced inside the pipe (especially a close nipple, which have threading its entire length, and therefore no surface for an outside wrench). As the wrench is turned, the unusual gear is forced to grip the inside of the pipe. As with a regular pipe wrench, the device is such that the grip on the pipe increases with the torque applied on the wrench.

They are a relatively cryptic but often adjectives tool.

Also called "internal pipe wrench".
