Your cart is empty. Each unit includes a 42mm rubber bellows paired with a CNC-machined aluminum base, designed to provide secure mounting and effective sealing in your model’s equipment cabin.
The flexible accordion-style rubber bellows isolate the push rod motion from water and debris, reducing the risk of leakage into the electronics compartment.
The aluminum base features an inner diameter of 6.5mm, is 16mm in length, and comes with a M9 threaded interface for secure installation and compatibility with a wide range of setups.
Ideal for RC boats using water-cooled systems, these bellows assemblies serve as a crucial upgrade for maintaining hull integrity and prolonging internal component life during high-speed or long-duration use.
