The Best Lube for Linear Switches
Researched by Johnny Alto · last updated July 29, 2026
Short answer: The best lube for linear switches is the Krytox GPL 205 Grade 0 (205g0). Krytox 205g0 is the undisputed community standard for linear switches, and the reasoning is simple: it is a thick Grade 0 PFPE grease that eliminates scratch and stem wobble while deepening the sound signature enthusiasts chase, and it is non-conductive and non-migrating so a lubed switch stays smooth for years. The main things to weigh are go thick for linears, grease, not oil,, budget ~1ml per ~90 switches;, and thin even coats only.
Krytox GPL 205 Grade 0 (205g0)
Krytox 205g0 is the undisputed community standard for linear switches, and the reasoning is simple: it is a thick Grade 0 PFPE grease that eliminates scratch and stem wobble while deepening the sound signature enthusiasts chase, and it is non-conductive and non-migrating so a lubed switch stays smooth for years. A little goes a long way, since 1ml covers roughly 90 switches. The honest limits: it is slow and tedious to apply by hand (an hour-plus per keyboard), and because it is thick, over-application makes switches feel sluggish or mushy, so thin even coats matter. It is also the most-counterfeited keyboard lube on Amazon, so buy from a listing with a strong review history to get genuine grease.

Representative image.Stock linear switches (Cherry MX Red, Gateron Yellow) often feel scratchy and sound pingy or hollow out of the box, and lubing is the single biggest upgrade for a smoother, deeper board. For linears you want a genuinely thick grease, because there is no tactile bump to protect. This is for anyone willing to spend an evening hand-lubing switches to turn a decent board into a great-feeling one. Here is the community standard, thinner options, and the mistake that ruins the feel.
How do the best options for lube for linear switches compare?
| Pick | Product | Why it makes the list |
|---|---|---|
| Top pick | Krytox GPL 205 Grade 0 (205g0) | Krytox 205g0 is the undisputed community standard for linear switches, and the reasoning is simple: it is a thick Grade 0 PFPE grease that eliminates scratch and stem wobble while deepening the sound signature enthusiasts chase, and it is non-conductive and non-migrating so a lubed switch stays smooth for years. |
| Best forgiving semi-fluid | TriboSys 3204 | A semi-fluid grease thinner than 205g0, so it is more forgiving if you tend to over-apply, and it doubles as a single lube if you also build tactiles. It smooths and deepens pure linears a touch less than 205g0. |
| Best for keeping speed | TriboSys 3203 | Thinner than both 205g0 and 3204, so it keeps more of a fast linear's snap and is hard to overdo. It does less dramatic smoothing and sound-deepening than thick 205g0. |
| Best value jar (with brush) | Krytox GPL 205g0 10g jar with brush | The same standard grease in a larger jar plus an application brush, enough to lube many boards. 10g is far more than a single build needs, and the jar is slightly messier to dose than a syringe. |
What should you look for in lube for linear switches?
A few things separate a good lube for linear switches from a frustrating one: go thick for linears, grease, not oil,, budget ~1ml per ~90 switches;, and thin even coats only. Weigh these before you buy.
- Go THICK for linears: Krytox 205 Grade 0 (205g0) is the target viscosity; the thinner 105 oil is a spring lube, not a standalone switch lube.
- Grease, not oil, on the stems and rails; oil is only for springs if you bother with spring lube at all.
- Budget ~1ml per ~90 switches; 3 to 5ml handles a full board plus spares, so do not buy a giant industrial tube.
- Thin even coats only: too much lube makes a switch sluggish and muted, and never use WD-40, Vaseline, or household grease (they attack the plastics and migrate).
Why thick, and why not too much
Lubing works by coating the sliding surfaces of a switch so the stem glides in the housing instead of scraping, which removes the scratchy feel and the high-pitched ping. Linears get the thickest grease (205g0) because there is no tactile bump to smother, so you can afford maximum smoothing, and the extra mass of a thick grease is also what deepens the sound toward the thock people chase. The catch is that more is not better past a point: flood a linear with grease and the stem drags through it, so the keypress turns sluggish and the sound goes dull and muted. The fix is technique, a thin even film brushed onto the rails and the sides of the stem, not a glob. It is slow hand work and it is largely irreversible without taking the switch apart again, so go light on your first switch, feel it, and only then commit to the rest of the board.
