Specialty Inflatable Fender Ball - 24" Diameter - Black

Seipel Marine Specialty Inflatable Fender Ball - 24" Diameter - Black

The Seipel Marine Specialty Inflatable Fender Ball (M3403) is a heavy-duty marine fender designed to provide superior hull protection during docking, rafting, and mooring. With a large 24-inch diameter spherical form, this inflatable ball fender delivers excellent impact absorption, helping prevent scratches, dents, and damage when coming alongside docks, pilings, or other vessels.

Crafted entirely in Milwaukee, Wisconsin from 41oz industrial grade black PVC material, this fender is built to withstand demanding marine environments including exposure to saltwater, UV rays, and changing weather conditions. Unlike many competitors, every tie-down point on this fender is RF welded — not glued — ensuring the highest possible bond strength under heavy load. Custom-formed stainless steel D-rings are included at each tie-down point for secure line attachment.

Every seam is fully welded and reinforced with extra welded PVC strips and additional seam tape for added protection and longevity. Direct UV-printed logos are applied without adhesive for a clean, lasting finish. The fender inflates quickly using the compatible M3100 air pump or any standard tube pump, and deflates easily for roll-up storage in tight spaces.

Suitable for big boats, sailboats, yachts, and any vessel requiring dependable fender protection, this ball fender can also serve as a mooring buoy or marker buoy thanks to its high-visibility black finish and large size.
