Specialty Inflatable Fender - 18" x 36" - Black

Seipel Marine Specialty Inflatable Fender - 18" x 36" - Black

The Seipel Marine Specialty Inflatable Fender is an 18-inch diameter by 36-inch long cylindrical fender engineered for serious boat protection. Handcrafted in Milwaukee, Wisconsin, every component of this fender is made in the USA using heavy-duty 41oz industrial-grade black PVC material, setting it apart from lighter-duty alternatives. The construction process relies exclusively on RF welding — no gluing — ensuring tie-down points and seams hold firmly under real marine conditions. Extra PVC seam tape is applied over all welds for added durability and long-term reliability.

Custom-formed stainless steel D-rings provide secure attachment points for fender lines, making this fender easy to rig on any vessel. It inflates quickly using the Seipel Marine M3100 air pump or any standard tube pump, and can be fully deflated and rolled up for compact, space-efficient storage when not in use. Direct UV-printed logos ensure branding stays crisp even after prolonged sun and saltwater exposure.

This fender is suited for large powerboats, sailing vessels, yachts, and any application requiring robust dockside protection. Its large diameter and length provide ample coverage for protecting hulls during docking and mooring. The product ships in a box measuring 7"H x 13"W x 17"L and weighs 7.6 lbs.

*IMPORTANT: Not to be used for towing, stopping a boat at high speeds, or as a flotation device.
