Loctite LOC39452 Clover Lapping Compound 120 Grit 1 Lb

Product Description

The LOCTITE LOC39452 is a silicon carbide grease-mix lapping compound designed for precision surface finishing and valve seating work. Sold under the Clover brand name, this compound uses 120-grit silicon carbide abrasive suspended in a grease carrier to cut and smooth metal mating surfaces. At 120 grit, it sits in the medium range of the lapping spectrum, making it well-suited for initial stock removal and flatting of surfaces before moving to finer grits. Licensed technicians and machinists use it when tight metal-to-metal seals are required. The grease base holds the abrasive in place on vertical or angled surfaces during lapping, reducing waste and improving control over the cut rate. Each unit is sold individually and weighs 1 pound.

This compound is used across multiple trades wherever metal surfaces must be lapped or reseated. Plumbers and valve technicians apply it when reconditioning gate valves, globe valves, and plug cocks. HVAC and refrigeration technicians use it when lapping compressor valve plates or service valve seats. Machinists and maintenance personnel use it for general surface conditioning of flat metal components. The 120-grit formulation is a common first-stage compound when a surface requires moderate material removal before a finish-lapping step.

Key Features

• 120-grit silicon carbide abrasive for medium-rate stock removal and surface conditioning
• Grease-mix carrier holds abrasive in position on vertical and angled work surfaces
• 1-pound container provides substantial working quantity for multi-piece or repeat jobs
• Suitable for valve seating, flat lapping, and metal-to-metal seal reconditioning
• Part of the Clover lapping compound line, a recognized standard in trade and industrial maintenance

Compatibility

Designed for use on ferrous and non-ferrous metal surfaces requiring lapping or surface conditioning, including valve seats, flat mating faces, and similar close-tolerance metal components. No specific OEM or model compatibility is stated for this compound.

Installation Notes

Lapping compounds are applied by qualified technicians or machinists working on disassembled valve or mechanical assemblies. Isolate and depressurize any system before disassembly. Apply compound sparingly to the lapping tool or mating surface and work in a consistent rotational or figure-eight motion. Thoroughly clean all lapping compound residue from surfaces before reassembly, as retained abrasive will accelerate wear on the finished assembly.
