Straight Line Sumo Max 450lb Ballast Bag
SUMO Skin 1000D: SUMO Sacs are made with our own flexible and puncture-resistant fabric, “SUMO Skin.” It has a durable 1000D polyester core that is heat laminated to lightweight PVC skins with a bonding agent. This sandwich construction is 150% stronger in tearing tests and 37% higher in tensile strength than SL competitors, making it the most durable ballast bag available.
SUMO Seams: Every SUMO sac is double welded to ensure a watertight seal. Their tough SUMO Skin is overlapped and hot air welded. You can see the smooth and clean seams on the outside of every bag, and a second welding operation applies an inch wide sealing tape to the inside of every seam.
LINK Valve: SL's unique LINKTM system provides a hassle free connection to your Sumo Pump, keeping your boat dry on the inside. The LinkTM Valve is watertight and can also be used as a convenient way to purge air from your bag.
1”NPT Valves: NEW and Improved threaded valves provide a perfect water tight seal, and have been pressure tested up to 6 PSI. SL's 1” NPT ports allow built in ballast systems to fill, drain and vent quickly for hassle free operation.
