These round O-Ring seals are made of high quality silicone which is high temperature resistance, non-toxic and no smell. This O-Ring gasket should work on any tray mount keyboard if it has a similar screw size. This modification is popular among mechanical keyboard owners from around the world. Since this O-Ring mod help the tray mount keyboard sound much better, it also improves the overall typing feel as well, making the keyboard feel much more even, softer and "poppy," thanks to the soft silicone rings the PCB/Plate sits on.
