Loctite 1330255 Threadlocker 243 Medium Strength 0.5 Ml

Product Description

The LOCTITE 1330255 is a single-use 0.5 ml capsule of Loctite 243 medium-strength threadlocking adhesive. Loctite 243 is an anaerobic liquid threadlocker that cures when confined between metal fastener surfaces, locking threaded assemblies against vibration loosening and preventing corrosion at the joint. The blue color coding identifies this as a medium-strength formulation, meaning fasteners can be removed with standard hand tools when disassembly is required. The oil-resistant formula maintains adhesion on fasteners that carry light surface oils, making it practical for field use on mechanical and fluid-handling equipment without requiring solvent cleaning in many applications.

Loctite 243 capsules are used across HVAC, plumbing, electrical, and general mechanical service work wherever threaded fasteners are subject to vibration or thermal cycling. The single-use capsule format eliminates concerns about bulk bottle contamination or partial curing and is well suited to service vans, field kits, and controlled-quantity dispensing. Each capsule delivers a precise dose for small to medium fastener sizes. The 100-capsule case quantity supports shop stocking and job-lot purchasing for service contractors.

Key Features

• Medium-strength formula allows disassembly with standard hand tools after cure
• Oil-resistant cure — adheres to lightly oiled fastener surfaces
• Single-use 0.5 ml capsule prevents contamination and waste
• Blue color coding for quick field identification as medium strength
• Anaerobic cure mechanism activates on contact with metal in the absence of air
• Sold in a 100-capsule case for shop and fleet stocking

Compatibility

Designed for use on standard metal threaded fasteners in mechanical, HVAC, plumbing, and industrial service applications where a removable medium-strength threadlocking compound is required.

Installation Notes

Apply threadlocker to clean or lightly oiled fastener threads immediately after breaking the capsule, then assemble and torque the fastener to the required specification. Allow adequate cure time before putting the assembly into service — full cure time varies with temperature, gap, and substrate metal. Disassembly of cured fasteners requires standard hand tools; apply localized heat if removal is difficult. Follow applicable codes and manufacturer torque specifications for the host equipment.
