Park Tool ASC-1 Anti-Seize Compound – 4 oz Tube

When components need to come apart as easily as they went together, Park Tool ASC-1 Anti-Seize Compound is the correct solution. Designed specifically for bicycle service, ASC-1 is formulated to reduce friction in threaded and press-fit connections while providing long-term protection against seizure, corrosion, and rust.

This compound is ideal for high-risk interfaces such as bottom bracket cups, pedal threads, seatposts, bolts, and press-fit assemblies—especially where dissimilar metals are involved. It performs reliably under extreme conditions, preventing galvanic corrosion and ensuring future serviceability.

Safe for use on steel, aluminum, and titanium, ASC-1 is a must-have for professional mechanics and serious home builders alike.

Why we use it at Go Grava:
Because nothing is worse than a seized component—and prevention is always easier than extraction.
