Phil Wood packs their own hubs and bottom brackets with this grease before they leave the San Jose factory, which tells you something about the confidence they have in the formula. The petroleum-based Waterproof Grease carries a premium classification from major bearing manufacturers and has been a shop staple since the 1970s for mechanics who want bearings that roll smoothly for years rather than months. The consistency stays soft enough to flow back onto bearing surfaces after use while remaining viscous enough to stay in place and seal out water and contamination.

The waterproof claim holds up in practice. Riders running Phil Wood grease in loose-ball hubs report opening them up after years of service, including rainy commutes and hose-downs, to find the bearings still coated and protected with no sign of water intrusion or rust. The grease fills the space around bearing assemblies and creates a barrier that prevents moisture from working its way past seals and into the races. This matters most for hub bearings, headsets, and bottom brackets where water exposure is constant and where failed seals mean replacing expensive components.

Beyond bearings, the grease works well on threaded interfaces and metal-to-metal contact points where you want corrosion protection and easier future disassembly. Bottom bracket threads, pedal spindles, seatpost interfaces, and stem bolts all benefit from a thin layer that prevents galvanic corrosion and seizing. The 3oz squeeze tube features a threaded cap for clean storage and can accept Phil Wood's portable grease gun for more precise application when you're packing bearings or working in tight spaces.
