A drop of Tri-Flow^® on metal bearing surfaces is all it takes to lubricate tuning gears, tremolos, roller bridges, truss rod nuts, tools and more. A luthiers favorite, this light viscosity penetrating lube contains super-slick Teflon^®, plus additives to help displace old gunk and prevent corrosion. It won't congeal and attract dirt like household oils. A little lasts a long time, and the handy pinpoint metal applicator puts it right where you want it.

Supplied in 0.25-ounce size

Apply Tri-Flow sparingly to the bearing surfaces of open-back tuning machines: a small drop at each worm gear post, and where the worm and crown gears meet. Don't overdo it! Unlike WD40^® and household oils that can collect dirt (which eventually impairs tuner operation), Tri-Flow contains Teflon^®, so frequent and excessive lubrication isn't necessary.
