Krytox GPL-205G0 0.35oz and GPL-105G0 0.35oz for Keyboard Switches and Springs Review (2026)

Two lubricants for two different jobs

Krytox 205G0 and 105G0 serve different roles in a switch lubing job, and buying them together saves sourcing them from two separate listings. GPL-205G0 is a thick grease meant for the switch housing, stem legs and rails, where its consistency helps cut down scratchiness and quiet down the sound of the stem sliding inside the housing during each keypress. GPL-105G0, by contrast, is a thinner oil rather than a grease, and is applied to the spring coils, since a thick grease on a spring can dampen the snap and feel of the return stroke rather than just quieting spring ping and crunch.

Why springs and housings need different products

Springs move differently than the sliding stem-and-housing contact inside a switch, coiling and uncoiling rather than sliding along a track, so a thinner oil coats the coils evenly without gumming up the motion the way a thick grease can. Using 205G0 grease on both parts, as some beginners do when they only own one lubricant, tends to leave springs feeling muted or springy in an unnatural way, while using only 105G0 oil on housings and stems will not cut down scratchiness the way the thicker grease does. Having both in one bundle removes the temptation to compromise by using a single product for both jobs.

How much a 0.35oz bottle covers

At roughly 10 grams each, a 0.35oz bottle of 205G0 grease is enough to lube a large number of switches with a light, controlled coat, since only a thin layer on the stem and housing is needed per switch. The same logic applies to the 105G0 oil for springs, where a small amount goes a long way when applied evenly rather than heavily across each coil. For most single keyboard builds, even a large full-size board with over 100 switches, one bottle of each should be more than enough, with room left over for a second build or touch-ups on stabilizers later.

The manual work this bundle does not remove

Buying both lubricants does not shorten the actual labor of a lube job, which typically means opening each switch, applying grease to the stem and housing with a small brush, reassembling it, and separately applying oil to each spring before the build goes back together. This process is time consuming across a full keyboard's worth of switches, often taking several hours for a first attempt, and is a deliberate choice enthusiasts make for a smoother, quieter and more consistent typing feel rather than a quick fix. Beginners should expect a learning curve on how much product to apply, since overapplying grease can dull sound and feel rather than improving it.

Who should buy this bundle

This bundle suits builders who have decided to hand-lube their switches and want both products needed for the job without placing two separate orders, rather than casual buyers looking for a fast way to quiet down a keyboard. It works well alongside other lubing tools like switch openers and fine brushes, which are not included here and need to be sourced separately before starting a build. Anyone not planning to open and individually treat each switch should skip this bundle, since neither product does anything useful on its own without the slow, manual lubing process carried out switch by switch across the whole board.
