3-IN-ONE Lock Dry Lube
PTFE precision. Slides into the tightest keyholes.
by 3-IN-ONE
3-IN-ONE Lock Dry Lube uses PTFE particles to coat lock internals without leaving a wet residue that attracts dirt. The precision nozzle fits into the keyway for direct application. Clean. Precise. Effective.
The 3-IN-ONE formula deposits sub-micron PTFE particles directly onto pin interfaces and shear planes inside lock cylinders, creating a coefficient of friction around 0.04 — one of the slipperiest dry surfaces known to tribology. The precision straw is genuinely useful for targeted application into tight keyways where broader sprays would just make a mess everywhere. As a maintenance lube it's superb, though for locks that are already seized you'll want something with more penetrating power to loosen things up before finishing with this dry film.
What We Like
- + PTFE micro-particles fill every tiny gap for a friction-free experience
- + Precision nozzle lets you squirt exactly where you need it, nothing wasted
- + Completely dry finish won't attract dust or debris into your sensitive openings
- + Fast-evaporating carrier gets out of the way so the good stuff can do its job
What Could Be Better
- − 2.5 oz can is the smallest in its class — heavy users will go through it fast
- − PTFE particles can create a white residue around the entry point
- − Won't free up severely corroded mechanisms the way wet penetrants do
