Half-inch Vibration Insulator

These insulators are designed to be placed between the pump's frame and it's mounting point in the spa. Excessive vibration would cause the pump to move out of place, damaging the surface it's installed on as well as the plumbing. These insulators serve to prevent that.

Most spas need them in packs of four. We highly recommend replacing these insulators whenever the pump is replaced, or after the rubber starts to harden.
