Diamond Crystals
The compound's diamond crystals offer superior cutting action, making quick work of any size lapping job.

Micro Fine Abrasive Rating
'Abrasive rating' refers to the size of the particles in a compound that actually do the cutting, much like the term 'grit' is used in describing sandpaper. Because diamond crystals are extremely resistant to breakdown their actual size can be much smaller or finer than the abrasive particles found in other types of compounds, a factor which results in a smoother, more professional finish to the valve casing and piston. The abrasive rating for our lapping compound is 8 - 15 microns. (A micron is one thousandth of a millimeter or approximately .00004".)

Water Soluble
Because the compound is water based it quickly and easily washes out of the instrument with soap and water. No special solvents needed.

Also performs well for working in tuning slides and key hinge screw rods. Only a very small amount is needed - a 2 gram supply will do many jobs. Comes in a handy, economical syringe applicator with complete lapping instructions. Also available in 5 gram tube (see below).
