VIBRATION ISOLATING RUBBER PAD

PT Mat Series of Anti-Vibration Pads with High Isolation Properties.

PT-MAT

Feature

Easy Installation

Reduces Soundproo�ng Requirements

Many Uses Just cut o� the required amount and install it.Can be used as isolation for equipment or plumbing support, wherever noise reduction is required. The pads can be used for impact load dissipation, vibration absorption, and reduction of movement during earthquakes, depending on the type of PT Mat and the pad's shape.

Applications● Vibration reduction for pumps, packaging machinery, etc.● Isolating pipes from their supports
