Loctite 542 Thread Sealant, Medium Strength, 10ml
Loctite 542 medium-strength thread sealant for metal pipes & fittings. Resists fuel, oil & vibration. 10ml bottle with DVGW approval.
Loctite® 542 is a medium-strength thread sealant specifically engineered for locking and sealing metal pipes, fittings, and other close-fitting cylindrical metal assemblies. It cures in the absence of air when confined between metal surfaces, creating a durable, permanent seal that prevents loosening and leakage caused by shock, vibration, and pressure fluctuations.
Its unique thixotropic formulation minimises product migration after application, ensuring the sealant stays precisely where it's needed, even on vertical surfaces or fine threads. This makes it an excellent choice for hydraulic and pneumatic systems, fuel lines, and general industrial fittings where a reliable, leak-proof connection is critical.
The cured sealant exhibits strong resistance to a wide range of industrial fluids, including fuels, oils, coolants, and hydraulic fluids, maintaining seal integrity in demanding environments. It provides an instant low-pressure seal, allowing for faster assembly and testing procedures.
A key benefit is its ability to permanently lock threaded connections against vibration loosening, enhancing the safety and longevity of assembled components. This product holds DVGW approval (EN 751-1: NG-5146AR0855), certifying its suitability for use in drinking water installations up to 90°C, adding to its credentials for professional and regulated applications.
Supplied in a convenient 10ml bottle with a precision applicator, it is designed for controlled dispensing and is suitable for use on metal threads only.
