Quality Guaranteed

To protect your boat, we use only the best metal valves to inflate DAN-FENDER products. For larger products, you’ll need a compressor since they come with a heavy-duty valve.
Buoyancies are calculated at 2 lb/sq inch (0.15 bar) and roughly 20°C/68°F. The maximum buoyancy values are provided for buoys/fenders when entirely submerged in freshwater.
DAN-FENDER recommends not to load products with more than 60% of the stated value.


The Warranty for DAN-FENDER products comes with a guarantee that covers any manufacturing defects. This guarantee is applicable when the products are used normally, as intended, and under the conditions they were designed for.
DAN-FENDER warranty will not cover damages caused by improper inflation, cuts, punctures, or exposure to chemicals that may cause the plastic to become sticky, degrade, or discolor. Additionally, any damages caused by abuse or neglect will void the warranty.
