On occasion, your poles may need more O-ring lubricant to help them easily slide in together.
Simply reapply a generous amount of the lubricant directly onto the rubber rings and then wipe them clean with a paper towel. This should help them slide easily into one another.
You can find O-Ring lubricant at the local hardware store or online. Many customers purchase their O-Ring Lubricant from an online hardware store called McMaster Carr. They are quick to ship and easy to find.
