Any help looking for a brass/copper, or any other metal tubing that are oil/ or?? impregnated tubing approx. dim. are 12" long or extruded lengths that could be cut to size, with a 1/8" to 1/4" ID. OD or wall thickness is not that important.

 

Oilite bushings are made from oil-impregnated sintered bronze material. I'm pretty sure you can buy them in continuous lengths which can be cut by you into tubes of whatever length you need. Try www.oilite.com for some information.
Of course these are bearings, not fluid tubes, so they won't be designed to work with ferrule-type tube connections.
