Power steering plug
Made a good seal in my P/S reservoir so I could pull a vacuum.

Just what I needed, priced well, shipped free
These stoppers are not the easiest things to find on the net and forget about finding in a local store. Good price, good quality, arrived in a couple days - who could ask for more.

These work perfectly as scupper plugs for a Liguid Logi kayak. Much more economical than those sold by the manufacturer and I think they are the same thing.

#11 Rubber stopper w/3/16 in hole
I needed this to do a vacuum on a new power steering unit install. The reservoir has a 2" opening and this item was ideal for inserting a small cone into the 3/16 inch hole and pushing it down onto the reservoir and using a hand pump to put a 15-20 psi vacuum on it to draw any and all air that was in the system. Was well worth the price. Got here in very short order and was put to work the day it came in.
