SUMO Skin 1000D: SUMO Sacs are made with their 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 their 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.
SUMO MAX FLOW LINK™ Valve: Their new SUMO MAX FLOW valve is a new 1 ½ Inch diameter high flow version of the Sumo LINK™ system. The SUMO Max Flow valve provides the same hassle free watertight connection to your Sumo Pump but with massive 50% LARGER intake. The Sumo Max system is 100% compatible with the classic Sumo and Big Bag ballast systems.
LINK™ Valve: Their unique LINK™ system provides a hassle free connection to your Sumo Pump, keeping your boat dry on the inside. The Link™ Valve is watertight and can also be used as a convenient way to purge air from your bag.
1”NPT Valves: NEW easy turning cap with a perfect watertight seal. Pressure tested up to 6 PSI. Their 1” NPT ports allow built in ballast systems to fill, drain and vent quickly for hassle free operation.
