Tube Coupler Stiffener
Stiffy heavy-duty tube coupler stiffiners feature a deep spiral groove for maximum epoxy adhesion. These super heavy-duty wall stiffeners are designed to be epoxied inside of our standard tube couplers to greatly increase their lateral strength. Snapping off a payload at the joint under high-speed stress (as occurs when flying at or near Mach speeds) is not a worry when you fly with a Stiffy.
NOTE: stiffys are not compatible with phenolic couplers.
NOTE #2: all stiffys on this page are manufactured at these lengths. We do not have longer versions!
