Esp`if coated in chain lube... Could you adapt a brake caliper nipple as a bleed port unit?

I used a plain screw and filed a flat on one side, with a Stat-O-Seal under the head. Anodizing is completely unnecessary. You can't see it, and it won't corrode any faster than the engine castings do. I was thinking more along the lines of preventing wear in the piston bore.

You could always go with a u-cup seal with a wear band, this way there would only be turcite (a form of Teflon) making contact with the aluminum.

I don't see bore wear as a problem, as long as you don't use an aluminum piston in an aluminum bore. The load is well centered so there are nearly no side loads, and movement is slight and not fast or often. Mine's still going after 34 years with a bare aluminum bore. Our brake cylinders are bare aluminum as well. Engine pistons too, for that matter.
On the other hand, you could anodize or install a sleeve if you wanted to, since it won't hurt.

Don't forget to install a bleeder screw... J I am still trying to figure that one out. A simple screw with a gasket or a proper bleed screw with a seat for the seal. TTN used a screw by the looks of it. Did anyone get one his units? This Ducati banjo bolt could work?

That is what I was looking for. Is it Ducati specific?

Don't think it is, I just knew Ducati has them but if you google "banjo bolt with bleeder" I think you will find other sourses for them.

I installed a similar bleeder in one of my karts years back and I seem to remember buying it from an auto supply co. It was not as tall as that and if I remember correctly it may have been for repairing a striped bleeder. It could have come from a automotive race shop. Keep looking their out there. (cheaper than DUCATI for sure).

Tidy wee unit... does it require an offset sprocket for clearance, or is it a direct bolt-up job? & current price/availability info too, please..
