Does a pipette that is sold unplugged work fine as-is, or do I need to plug it?

I have a couple of plastic pipettes for measuring essential oils. They've been great except for the oils dissolving the plastic (!) so I'm looking at glass pipettes such as the Sibata 25ml serological pipette, which I found for a decent price.
It's not plugged (as in, the length of cord-looking stuff in the narrow bit at the top that my plastic pipettes have). I've researched and found one reference to plugging pipettes as something done in a lab, but no instructions.
I don't actually know what the plug does, will the pipette work fine without a plug? Maybe the plug just protects the pipette suction pump from liquid if I overdo it? If I have to plug it, any advice on what to use and how to do it?
Thanks for any advice you can offer.
