Compression rings

Compression Rings

Die Co. compression rings ensure a snug fit in knob-to-shaft assemblies.

Die Co. compression rings provide secure, even tension between knobs and mating shafts. Made from spring steel, they ensure a snug fit even when knobs are changed. They easily expand to attach to knob hubs.

Compression rings also can serve as a shim, compressing to securely hold a tube when it is inserted in a panel.
