Loctite LOC29031 Thread Locker Sealant Wicking Grade

Product Description

The LOCTITE LOC29031 is a wicking-grade liquid thread locker and sealant supplied in a 1.69 oz (50 ml) bottle. It is formulated to wick into pre-assembled metal threaded joints by capillary action, filling the gap between mating threads and curing in place to lock and seal the connection. Designed for both low- and high-pressure applications, it seals immediately for low-pressure testing and achieves full cure strength to match the burst rating of most metal piping systems. Plumbers, pipefitters, and HVAC technicians install this product on metal pipe and fitting assemblies where post-assembly sealing is required.

This thread locker is suited for residential and commercial plumbing, HVAC refrigerant and hydraulic lines, and general industrial piping where threaded metal joints must be secured against leakage. Its wicking-grade viscosity makes it appropriate for joints that are already assembled and cannot be disassembled for conventional sealant application. It is applied after assembly, drawing into the thread engagement zone under its own capillary action without requiring disassembly of the joint.

Key Features

• Wicking-grade formulation penetrates pre-assembled threaded metal joints by capillary action
• Seals instantly for low-pressure testing after application
• Cures to the burst strength of most standard metal piping systems when fully hardened
• Suitable for both low- and high-pressure service applications
• Compact 1.69 oz (50 ml) bottle for bench or field use

Compatibility

Designed as an OEM-style liquid thread sealant for use on metal pipe and fitting assemblies in plumbing, HVAC, and industrial piping systems.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or HVAC technicians following applicable IPC or IFGC guidelines for thread sealing compounds. Ensure the system is depressurized and drained before servicing any threaded joint. Apply the wicking-grade sealant to the exterior of the assembled joint and allow capillary action to draw it into the thread engagement zone before returning the system to pressure. Allow full cure time before subjecting the joint to maximum system pressure.
