Sounds to me like your talking more about the rod wiper than an actual rod seal. Most rod seals are of a relatively high durometer but not as stiff as an actual plastic like your describing. The wipers, on the other hand, are typically made of alot tougher material than the actual seals, and that, coupled with the shape is not condusive with the use of the tool DH suggests. That said I don't know of anyone making a tool to help insert a seal/wiper/etc made out of that hard of a material.
Now if it's actually a U seal of some description then the instillation tool DH recommends can't be beat. I spend alot of years putting seals in with no tool, and when those came out I would have given a mint for one as they make putting a seal into it's hole alot easier, especially when it's a small diameter seal going down into a hole your fingers won't fit in.
With all of that said, the harder seals will typcally benefit from being soaked in HOT water to soften them up a bit before putting them in. Too, there are small diameter buffer seals (don't figure that's what you have as they typically have an oring energizer in the groove behind them)that need to be prestretched before installing it in the bore. Failure to do so on those will typically end with the seal being messed up when the rod is insterted through it.

Today's Featured Article - Oil Bath Air Filters - by Chris Pratt. Some of us grew up thinking that an air filter was a paper thing that allowed air to pass while trapping dirt particles of a particles of a certain size. What a surprise to open up your first old tractor's air filter case and find a can that appears to be filled with the scrap metal swept from around a machine shop metal lathe. To top that off, you have a cup with oil in it ("why would you want to lubricate your carburetor?"). On closer examination (and some reading in a AC D-14 service manual), I found out that this is a pretty ingenious method of cleaning the air in the tractor's intake tract.
