Loctite LOC24241 Threadlocker 242 Medium Strength 250 Ml

Product Description

The LOCTITE LOC24241 is a medium-strength liquid threadlocker designed to secure and seal threaded metal fasteners in mechanical and plumbing assemblies. Supplied in a 250 ml bottle, this anaerobic adhesive fills the gaps between mated metal threads and cures to prevent loosening from vibration, shock, and thermal cycling. At medium strength, it allows for disassembly with standard hand tools, making it well suited for fasteners that require periodic service. Licensed HVAC technicians, plumbers, pipefitters, and mechanical contractors use this product on a routine basis during installation and maintenance work.

LOC24241 is applicable across a wide range of residential and light commercial mechanical systems. It performs in both low-pressure and high-pressure threaded connections, sealing instantly upon assembly for low-pressure testing and reaching full cure strength adequate for most piping system burst pressures. It is appropriate for use on metal-to-metal threaded joints in HVAC equipment, plumbing rough-in, and general mechanical assemblies where a removable, vibration-resistant thread lock is required.

Key Features

• Medium strength formula allows disassembly with standard hand tools after curing
• Anaerobic cure fills thread voids and prevents leakage under pressure
• Seals instantly on assembly for low-pressure system testing
• When fully cured, seals to the burst strength of most piping systems
• 250 ml bottle volume suits regular shop or field use
• Designed for low- and high-pressure threaded metal applications

Compatibility

Designed for use on threaded metal fasteners and pipe fittings in mechanical, plumbing, and HVAC assemblies where a medium-strength, removable anaerobic threadlocker is specified.

Installation Notes

Application is performed by a qualified mechanic, pipefitter, or plumber in accordance with the applicable mechanical or plumbing code for the jurisdiction. Clean and degrease both mating thread surfaces before applying the threadlocker to ensure proper anaerobic cure. Allow adequate cure time before pressurizing the system; partial cure is sufficient for low-pressure testing but full cure is required before full system pressure is applied. Wear appropriate chemical-resistant gloves and eye protection when handling liquid adhesive compounds.
