Chinese oilers

My hobby seems to have evolved into buying machine tools, taking them apart and then moaning about what I find.

This one has lovely oilways connected to ghastly brass oilers.

How were these oilers fitted? How do I get them out so I can replace them with pipework?

I may be corrected , but i think they are just a tight fitting parallel type. I did see a thread somewhere on the net where the guy screwed a self tapper in & then used a claw hammer to extract them.

As said not too sure. Maybe wait for a better answer.

Assuming they are pressed in (most are) and if you aren't bothered about destroying them, then a suitably sized self-tapping screw driven into the hole should enable you to lever them out with pliers or similar.

They look like Button Oilers, which are just a press fit in the hole. I've removed some without damaging them by prying with a Stanley Knife. Difficult ones come out by turning a wood-screw into the hole and pulling it. Inside the oiler a spring loaded ball-bearing is pushed against the entrance to seal it, and there's room to get enough wood-screw thread inside to get a good grip. It destroys the oiler though!

You need to use a penknife blade to ease them out. If that fails, run a blade round the hole until it gets big enough for the ball to pop out and then I have used a tap screwed in a couple of turns to pull the remains out. These button oilers come in metric and inch sizes, you have to measure the hole. The Tom Senior mill had three sizes on it.

Steve's self tapper is a good method.

Excellent, you are clever. Now the really tricky bit...

What do I type into eBay, Amazon, AliExpress etc to find these connectors?

They are I believe Norgren Enots type compresion fittings. You can substitute push in fittings made by Norgren, Legris and Festo. You need to specify the thread size of fitting & OD of tubing.
