Hi Jim,

The collapsible variety (telescoping) have two internal o-rings and a
spring to provide tension, those were the o-rings I was wondering about.
The nice thing about them is that they can be installed without pulling a
head & are easily removed. I have new seals for the ends that came in my
Reinz kit. Thanks for the tip on rejuvenating the old ones, I will be
re-using some of them.

Cheers, Tom
