Tri-Flow
Tri-Flow Superior Lubricant with PTFE
PTFE-fortified. Precision application. One lube handles everything.
by Tri-Flow
Tri-Flow is the Swiss Army knife of lubricants. PTFE-fortified for extra slickness, it penetrates, lubricates, and prevents rust in one application. The drip bottle gives you precision control for delicate work.
Tri-Flow has earned its cult following in the locksmith and cycling communities for good reason — the suspended PTFE particles (essentially microscopic Teflon) fill surface imperfections at the microscopic level, creating a friction coefficient that heavier oils simply cannot achieve. The drip bottle applicator is a masterclass in precision delivery, letting you place a single drop exactly where it's needed without any messy overspray. It's not trying to be everything to everyone, and that restraint is what makes it exceptional — smooth, controlled, low-friction performance in tight spaces.
What We Like
- + PTFE micro-particles fill in every tiny imperfection for an impossibly smooth finish
- + Precision drip bottle lets you control exactly where and how much you apply
- + Light viscosity flows freely into the most delicate, intricate mechanisms
- + Versatile formula handles everything from locks to bearings to hinges
What Could Be Better
- − Tiny 6 oz bottle doesn't last long when you're servicing multiple pieces
- − Too thin for heavy-duty applications — this is a finesse product, not a powerhouse
- − PTFE particles can clog very fine mechanisms if you get overzealous with application
Who Should Buy This
Precision hobbyists, locksmiths, and anyone who appreciates a delicate touch over brute force. The thinking person's lubricant for those who value technique and control.
