Spare O-rings for the Master Track Wrapper. Sold in a three-pack!
Three-pack contains two large O-rings and one small O-ring to match up with one roller unit.
“By the way, the new rings work great on my wrapper. Just need to pre stretch them a bit.” – Rick M.
Pre-stretching, as Rick suggests, is a great idea. This will make it a little easier to ease those snug, new O-Rings into the grooves on the roller wheels.
