Specialty Inflatable Fender - 18" x 42" - Black

Seipel Marine Specialty Inflatable Fender - 18" x 42" - Black

The Seipel Marine Specialty Inflatable Fender in the 18" x 42" configuration is a heavy-duty, large-format cylindrical fender engineered to protect big boats, sailboats, yachts, and any vessel requiring reliable dockside protection. Constructed entirely in Milwaukee, Wisconsin from 41oz industrial-grade black PVC material, this fender delivers exceptional toughness and longevity in demanding marine environments.

Unlike lesser fenders that rely on adhesive bonding, every seam on the Seipel Marine Specialty Fender is RF (radio-frequency) welded for a permanent, watertight bond. Additional welded PVC strips are applied over all seams, and extra seam tape is layered onto the welds to provide maximum strength and resistance to splitting or delamination over time. Custom-formed stainless steel D-rings and special tie-down points give you secure, flexible attachment options for virtually any railing or cleat configuration.

The fender inflates quickly using any standard tube pump or the Seipel Marine M3100 air pump, and deflates just as easily so it can be rolled up for space-saving storage aboard or ashore. Branding is applied via direct UV printing so logos and markings resist fading through seasons of sun and saltwater exposure.
