Each mount in comprised of high quality fasteners and industry leading Sorbothane visco-elastic polymer. The unique vibration damping properties allow it to behave like a fluid but retain its shape for millions of cycles, far exceeding the limits of other materials like silicone, rubber and neoprene. These mounts are designed for compression applications where very low shear force is present. When installing use high-quality thread deforming lock nuts or double jam nuts to ensure that your connections do not vibrate loose. Not recommended for high amplitude vibrations. This product contains plasticizer and may cause discoloration to materials that are in contact with it for extended periods of time. Made in the USA from US materials.
