Well I think a cork would work good for 3/4 pipe. For one inch you could make your own out of hotglue.

What is the point of "need ideas" just try to find stuff that fits and use your imagination.

first search and try before you make a topic
there is a how-to on making epoxy pistons
if you want to use hot glue make sure you use anti stick and first melt it and then pour it in the right pipe size
just try so materials that are cylinders with the right diametre
