Loctite LOC39426 Clover Lapping Compound 220 Grit 1 Lb

Product Description

The LOCTITE LOC39426 is a silicon carbide grease-mix lapping compound designed for precision surface finishing and valve seating work. Sold under the Clover brand line, this compound uses 220-grit silicon carbide abrasive suspended in a grease carrier to cut metal surfaces consistently and evenly. At 1 pound per container, it provides enough material for repeated lapping cycles in a shop or field environment. Machinists, millwrights, and maintenance technicians use this compound when tight surface contact between mating metal parts is required for a proper seal or fit.

This lapping compound is used across a wide range of industrial and mechanical applications including valve grinding, gear lapping, and precision flat-surface mating. The 220-grit classification places it in the medium-fine range, making it suitable for intermediate stock removal and surface refinement after coarser lapping stages. It is commonly used in pump repair, engine rebuilding, and hydraulic valve service where metal-to-metal sealing surfaces must be lapped to a consistent finish.

Key Features

• 220-grit silicon carbide abrasive for medium-fine surface finishing
• Grease-mix carrier holds abrasive in suspension during lapping
• 1-pound container suitable for repeated shop or field use
• Consistent grit sizing supports repeatable surface finish results
• Compatible with a wide range of ferrous and non-ferrous metals

Compatibility

Designed as an OEM-style lapping compound for general metal surface finishing applications including valve seats, pump components, and precision mating surfaces in mechanical and industrial service work.

Installation Notes

Apply lapping compound only to clean, dry metal surfaces free of oil, debris, and prior compound residue. Use appropriate lapping tools such as lapping plates, hand laps, or valve grinding tools depending on the application. Wear nitrile gloves and eye protection when handling abrasive compounds. Thoroughly clean all lapped surfaces with solvent before final assembly to remove residual abrasive, which can cause accelerated wear if left in the assembly.
