Why You’ll Want It
Over time, ballast plugs can wear out, leak, or get lost. This replacement air release plug with O-ring ensures your ballast bags stay sealed tight and perform their best, season after season.

FATSAC's are proudly made in the U.S.A. in Milwaukee, Wisconsin. Their Pro X Series Quick Connect fat sacs are made of a 3 layer Valmex material, which is similar to the materials used in making river rafts and inflatable boats. The extreme durability means it is nearly impossible to puncture these bags. These bags are handmade with strict quality control. The extra wide seams are welded and taped. Fatsac is the only ballast company that makes the extra step to tape the seams, making one more layer of protection against any malfunction. This attention to detail and quality is the reason most boat manufacturers use them for their OEM bags, in fact if you have a wake boat with stock ballast from the past 10 years I can almost guarantee there is already a fatsac in it whether you know it or not. Fatsac has long been a pioneer in wakesurfing and wakeboarding and is considered the original wake ballast co.
