Wrinkle Band Ring Compressor

One Single Adjustment Does All Cylinders
Compresses piston rings with less ring contact and lower friction, allowing pistons to slide in easier and faster.
Cam lever operation requires just one setting adjustment for fast piston to piston change. Ideal for barrel cylinders which install over piston, as the band separates.
