Loctite LOC39523 Clover Lapping Compound 400 Grit 1 Lb

Product Description

The LOCTITE LOC39523 is a silicon carbide grease-mix lapping compound formulated for precision surface finishing and valve seating work. Sold under the Clover brand name, this 1-pound container delivers 400-grit abrasive action in a stable grease carrier that keeps the compound in place during hand lapping, honing, and fit-testing operations. The fine 400-grit particle size makes it suitable for final finishing passes where a smooth, tight mating surface is the goal. Licensed tradespeople and skilled machinists reach for this compound when metal-to-metal seating accuracy is critical to system performance.

This compound sees regular use in valve lapping, pump seat reconditioning, and precision mechanical fitting across plumbing, HVAC, and industrial maintenance applications. It is applied by hand or with a lapping tool to ground metal surfaces that require intimate contact to seal reliably under pressure. The grease-mix base clings to vertical and angled seats without running off, making it practical for in-place valve service where disassembly is limited. A 1-pound container provides sufficient volume for multiple service calls or a single high-volume reconditioning job.

Key Features

• Clover lapping compound formulation trusted in trade and industrial maintenance
• Minimum order quantity of 6 units per order

Compatibility

Designed as a general-purpose lapping compound for use on ferrous and non-ferrous metal valve seats, pump components, and mating surfaces requiring precision finishing in plumbing, HVAC, and mechanical maintenance applications.

Installation Notes

Apply only to clean, dry metal surfaces that have been inspected for damage before lapping begins. Always isolate and depressurize the system and shut off all fluid or gas supply before performing any valve or seat work. Use the minimum amount of compound necessary to achieve the desired surface finish, and thoroughly clean all residual compound from mating surfaces before reassembling and returning the system to service. Surface lapping and valve reconditioning work should be performed by a qualified tradesperson familiar with the relevant system type and applicable service codes.
