Inner tubes that are used often will last longer as this maintains the elasticity and flexibly of the rubber. During the manufacturing process, the tube manufacturer adds a protective compound to the rubber formula. Regular use causes the inner tube to flex and compress, pushing this protective substance to the surface. This doesn’t happen in an unused inner tube, so the rubber is more vulnerable to damage from ozone and oxidation. If you plan to keep the Jungle Jumparoo frame outdoors we suggest sealing the unit at least once per year.
