LOCTITE 243 50ml – Medium Strength Oil-Tolerant Threadlocker

Genuine LOCTITE 243 – Medium Strength Oil-Tolerant Threadlocker

Genuine LOCTITE 243 comes in a convenient 50ml tube and is designed for metal threaded fasteners that endure vibration and exposure to oil. This formulation supports dependable performance in assemblies where disassembly may be needed, and where parts encounter oil during service. While the packaging notes an expiry of 2017, the product is known for its oil tolerance and versatility in challenging conditions.

LOCTITE 243 offers a practical balance of strength and reworkability. It is formulated to resist loosening on fasteners subjected to repeated motion, yet remains removable with standard hand tools when servicing is required. This makes it a sensible choice for maintenance scenarios where ease of disassembly is part of the workflow.

Key benefits

• Effective on all types of metal threaded fasteners, delivering consistent performance across common materials.
• Prevents loosening in vibrating assemblies such as pumps, motor mounts, gear boxes, and presses.
• Oil-tolerant formulation maintains bonding in environments where lubrication is present or introduced during service.
• Medium functional strength with measurable torque characteristics, including a typical 22 °C breakaway torque around 20 Nm for M10 bolts.
• Long-term temperature resistance up to +150°C, helping maintain grip across a range of operating conditions.

Usage considerations and packaging details

• 50ml tube is part of a 140ml bottle; about 35% of the bottle content is actual glue, with air included to help stability.
• Expiry is listed as 2017 on the packaging, so check current stock notes for shelf life guidance.
• Best suited for assemblies where disassembly with hand tools is anticipated and where oil exposure may occur during service.

In real-world settings, technicians and engineers often value the balance between holding power and ease of removal. The oil-tolerant design supports workflows with lubrication or minor oil leakage without sacrificing the ability to service parts when needed. As with any bonding solution, results can vary depending on bolt size, material, surface condition, and operating environment, so select a threadlocker that aligns with your task requirements.

Notes on expectations

This threadlocker offers a practical option for moderate clamping needs on metal threads facing vibration and oil exposure. It is not a guarantee of performance in every scenario, but it is designed to support reliable assemblies where maintenance access is part of the process.
