NSF International Certified to ANSI/NSF Standard 61 for use in commercial and residential potable water systems not exceeding 82° C.
1. PRODUCT DESCRIPTION
LOCTITE® 243™ is designed for the locking and sealing of threaded fasteners which require normal disassembly with standard hand tools. The product cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration. Particularly suitable for applications on less active substrates such as stainless steel and plated surfaces, where disassembly with hand tools is required for servicing. The thixotropic nature of LOCTITE® 243™ reduces the migration of liquid product after application to the substrate.

4. Directions for use For Assembly 1. For best results, clean all surfaces (external and internal) with a LOCTITE® cleaning solvent
and allow to dry. 2. If the material is an inactive metal or the cure speed is too slow,
spray all threads with Activator 7471™ or 7649™ and allow to dry. 3. Shake the product thoroughly before use. 4. To prevent the product from clogging in the nozzle, do not allow the tip to touch metal surfaces
during application. 5. For Thru Holes, apply several drops of the product onto the bolt at the nut engagement area. 6. For Blind Holes, apply several drops of the product down the internal threads to the bottom of the hole. 7. For Sealing Applications, apply a 360° bead of product to the leading threads of the male fitting,
leaving the first thread free. Force the material into the threads to thouroughly fill the voids.
For bigger threads and voids, adjust product amount accordingly and apply a 360° bead of
product on the female threads also. 8. Assemble and tighten as required.
5. Storage Store product in the unopened container in a dry location. Storage information may be indicated on the product container labeling. Optimal Storage: 8 °C to 21 °C. Storage below 8 °C or greater than 28 °C can adversely affect product properties Material removed from containers may be contaminated during use. Do not return product to the original container.
