Valve Lapping Compound

ROCKET Grinding Pastes / Lapping Compounds are manufactured by combining carefully graded abrasives with a specially developed vehicle of soft cream-like consistency.
In addition to uniformly dispersing the abrasive this vehicle effectively and permanently suspends it to eliminate settling out, yet it reduces rapidly to a smooth thin film when subjected to the slightest frictional heat. Non-toxic and non-corrosive to all metals, this unique formulation will in fact, prevent rusting of steels. Because it resists breakdown by heat it will prevent "Galling" or "Seizing" during severe or high precision lapping operations.
In special applications, thinning may be necessary and oils such as: lard, olive, or light mineral are compatible with this vehicle.
Residue on the lapped parts is easily removed by any alkaline cleaners.
