Small O-rings - For screw-in stabilizers

Previously called 60% Thin

S for small and more importantly... Screw in Stabilizers! These are intentionally thinner than your normal o-rings to allow the use of the screw in stabs on the backspace and spacebar.

Please only buy this o-ring if you are using screw in stabilizers for your 60% keyboard.

Thickness: ~3mm

Diameter: ~305mm

Medium O-rings

Previously called 65%

M for medium! These are standard sized to fit most 65% keyboards as well as some 60%.

There is also a chart for you to see if your board is on our checked list. If it is not on our chart, we do not recommend buying it, and you are buying at your own risk.

Thickness: ~3.5mm

Diameter: ~325mm

Large O-rings

For 70/75% keyboards.

X (TKL) O-rings

X for TKL! These are standard sized to fit most TKL keyboards

There is also a chart for you to see if your board is on our checked list. If it is not on our chart, we do not recommend buying it, and you are buying at your own risk.
