Krytox 205g0 Switch Lubricant
Krytox 205g0 Switch Lubricant
Krytox 205g0 is the community-standard thick lubricant for mechanical keyboard switches: a smooth Grade 0 grease that takes the scratch out of linear switches, quiets spring ping, and deepens the sound of every keystroke. This 3 mL container (about 5 g) is the right size for a first lubing project — generally enough to cover a full board of switches with thin, even coats.
Key specifications
- Thick switch lubricant with a Grade 0 (soft grease) consistency
- Designed for linear switch rails, stems, and springs
- Reduces scratchiness, spring ping, and hollow case noise
- 3 mL container — approximately 5 g of lubricant
- Long shelf life when stored sealed at room temperature
What's in the box
- 1 × 3 mL container of Krytox 205g0 switch lubricant (approx. 5 g)
Compatibility
Works with all MX-style mechanical switches (Cherry, Gateron, Kailh, and others). It is the classic pairing for linear switches; use it very sparingly on tactile switches, since a thick lube can soften the tactile bump. Also commonly used on stabilizer wires and contact points.
Who is this for
Anyone doing their first switch-lubing project, or an experienced builder restocking the most-used lube on the bench. If your linear switches feel scratchy or sound thin, this is the single highest-impact upgrade you can make.
Frequently asked questions
How much lube do I use per switch?
Less than you think — a thin, even film on the rails and a light coat on the spring ends. Over-lubing makes switches feel sluggish.
Can I use 205g0 on stabilizers?
Yes. It is widely used on stabilizer wires to eliminate rattle, often alongside a thinner lube on the slider contact points.
What is the difference between 205g0 and 105?
205g0 is a thick grease for switch rails and springs; 105 is a thinner oil typically used for springs and tactile switch legs. Most builders start with 205g0.
Do I need special tools?
A small brush for application and a switch opener help a lot. A lube station keeps things organized if you are doing a full board.
