LOCTITE® 577 is designed for the locking and sealing of metal pipes and fittings as well as other threaded assemblies. The product provides an instant, low-pressure seal for metal pipes and fittings. It will not creep, shrink or shred. It has excellent chemical and thermal resistance and offers less migration of liquid product after application.

• Medium-strength, general purpose thread sealant for sealing metal threads
• Suitable for all metals
• Instant low pressure seal
• Excellent chemical resistance
• Locks connection against vibration-induced loosening and other stresses
• Easy to apply
• Cures on active and inactive metals
• NSF P1 Reg. No. 123001
• DVGW Approval (EN 751-1): DVGW Reg. No. NG-5146CQ0312

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 with LOCTITE®
   SF 7471™ or LOCTITE®
   SF 7649™ and allow to dry.
3. 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 thoroughly fill the voids. For
   bigger threads and voids, adjust product amount
   accordingly and apply a 360° bead of product on the
   female threads also.
4. Using compliant practices, assemble and wrench tighten
   fittings in accordance with manufacturers
   recommendations.
5. Properly tightened fittings will seal instantly to moderate
   pressures. For maximum pressure resistance and
   solvent resistance allow the product to cure a minimum of
   24 hours.

For Disassembly

1. Remove with standard hand tools.
2. Where hand tools do not work because of excessive
   engagement length or large diameters (over 1"), apply
   localized heat to approximately 250 °C (480F).
   Disassemble while hot.

For Cleanup

1. Cured product can be removed with a combination of
   soaking in a LOCTITE®
   solvent and mechanical
   abrasion such as a wire brush.
