Kalrez Black Dots & Washers

Made from DuPont Kalrez 7075 perfluoroelastomer. Extensive experimenting with this material and use in our UltraSonic Rx Damping Instruments have confirmed this material to be superb at absorbing micro-vibrations and providing superior decoupling between surfaces subject to extreme heat. Though the material is very expensive, it's excellent for mounting transformers and other audio electronic applications. Washers are flexible and compliant yet more firm than standard grungebuster washers. Thickness is .060" (1.52mm) with a continuous service temperature of 620° F (327° C).

UltraSonic Binding Post Washers

Hand-made dielectric fiber washers snap into place laterally, between spade and tightening nut. Smooths out harsh microphonic vibrations; partially decouples nut from signal path, allowing a more-direct signal; reduces risk of stripping threads; provides a generally "tighter" yet expansive musical result. For 1/4" or 5/16" posts. Washer is very firm, slightly flexible, .062" thick.

for 1/4" or 6mm binding post
$8.95 / set of 4

for 5/16" or 8mm binding post
$9.95 / set of 4

"Washers increased control and tightness on bottom end, cleaning meanwhile another bit of dust all over the band. They really work well in damping electromechanical vibration coming back from speakers coils."–Ermanno Butteri, San Benedetto, Italy

"The speaker binding post washers have an impact. It's not huge, but just a little more black in the background, with details coming out even better."–JW Verheij, Rotterdam, Netherlands
