Anti-Vibration Pads
Anti-Vibration Pads
These sound dampening pads work best with heavy external water pumps and large air pumps and recirculation blowers where there is significant vibration being transferred from the pump to the surface the pump is mounted too. Made from foam pads with a ribbed rubber lining.
The latest generation in vibration dampening technology. The most effective vibration dampening pad available on the market. The EVA Pad was tested against other pads at four different vibration settings. In the most severe vibration extremes, the EVA Pad outperforms cork and
rubber by a margin of greater than 3:1! This is due to the special composite foam center which is much more structurally sound than cork. It is not affected by oils or chemicals that can break down cork and is much more effective at vibration dampening than solid rubber. All this at a very competitive price. Designed to withstand 50 psi.Starting at: $3.95
