Super-Bands™ are modern polyurethane rings for pinball machines that play better and last longer than traditional pinball rubber. Tested by professional pinball players and commercial operators, Super-Bands™ are proven to reduce maintenance and increase playability in all pinball machines. Super-Bands™ are carefully engineered to maintain the same rebound, or bounce, of traditional soft 45-durometer rubber that pinball designers and professional players prefer.
More Durable: Advanced customized polyurethane compound is more resistant to abrasion, ozone, and ultraviolet light than traditional rubber.
Better Control: Super-Bands™ have equal to or better tactile response than standard rubber and allow for great ball control by any skill level player
Vibrant Colors: High-gloss surface with deep translucent colors look great on any game.
Lower Maintenance: Super-Bands™ are less porous and wipe clean with a cloth. They don’t absorb dirt like traditional rubber.
