Diversitech MP-4E EVA Anti-Vibration Pad 4x4 inch Square by 7/8 inch Thick.

E.V.A. PAD:  The best performer E.V.A. (Extreme Vibration Attenuation) is the latest generation in vibration dampening technology.

In the most severe vibration extremes, testing shows the E.V.A. pad outperforms cork and rubber by greater than 3:1 and outperforms our competitor’s “waffle” pad by greater than 8:1. The enhanced performance comes from the special composite foam center which is structurally more sound than cork. E.V.A. is not affected by oils or chemicals that can break down cork and is much more effective at vibration dampening than solid rubber. Designed to withstand 50 psi.
