Extend the Service Life of your RIB

Upgrade your original sponsons with the superior fit and long lasting performance of Wing sponsons.

Wing polyurethane has twice the puncture resistance and four times greater abrasion resistance than Hypalon. The standard expected service life of a Wing polyurethane tube is 7-8 years—versus only five for a Hypalon tube—with Wing tubes running stiff, strong and still in service after 12-14 years is increasingly common.
