Gladiator Sonix III 3-Person Towable Tube With Lightning Valve

Catalog Item # 109558

Fast fun at Sonix speed!

This cockpit-style towable tube features heavy-duty fully covered PVC construction; inflatable backrests and seat bottoms; soft foam handles with EVA knuckle guards; and quick-connect tow hook. Lightning valve inflates/deflates 57% faster than the Boston valve. Overton's recommends purchasing one of our Inflator/Deflator pumps (items #109532 #109572) that come with an adapter sized to fit the new Lightning valve. The Lightning Valve is similar to the Boston Valve except that it is attached to the towable so there are no parts to keep up with or lose. The wider opening inflates and deflates 57% faster than the Boston Valve. An interior flap prevents air from escaping even if the cap is not in place. Inside diameter of the valve measures 30mm.
