FATSAC Wally Plug - W731

FATSAC Wally Plug

The FATSAC Wally Plug (W731) is a purpose-built bag plug fitting used to seal unused valve ports on Fly High Pro-X Series ballast sacs. All FATSAC fittings are machined in-house and are proprietary to the brand, giving FATSAC full control over quality and allowing them to work creatively with OEM and custom sac customers to meet specific requirements. The Wally Plug was affectionately named after the machine shop manager in charge when it was first created, and it has since become a standard fitting included with all Pro-X Series products.

The fitting uses a 3/4" BPST sac valve thread pattern that matches the proprietary thread design found on Fly High bags, creating a perfect water-tight seal that will not leak or back out over time. An O-ring is included at the seal point to further guarantee an airtight closure. Off-the-shelf Fly High bags include the required number of Wally Plug fittings, but if you have misplaced one, want to keep extras on hand, or have purchased a custom or semi-custom Fly High ballast bag, this is the fitting you need to seal any unused ports.

FATSAC ballast fittings are designed to make connecting pumps and hoses to Fly High Pro-X Series Ballast Sacs a quick and simple task — no more struggling with old waterbed valves or dealing with water spilling inside the boat. Simply twist, pull, replace, and you're ready to go. FATSAC offers a full range of fittings that work together to adapt to any ballast system need.
