WEICON WEICONLOCK AN 302-75 Anaerobic Thread Sealant is an anaerobic industrial adhesive solution developed to provide sealing and reduce loosening in pipe and threaded connections. Its green, fluorescent nature helps make the applied bead easier to control. Thanks to its high viscosity, it supports controlled application by forming a film on the threads that can stay in place without running. Because it cures in a high-strength class, it stands out for connections where permanent sealing is required and disassembly is difficult.<\/p>\n
AN 302-75 works as an anaerobic, resin-based industrial adhesive that cures in narrow gaps between metal surfaces once contact with air is cut off. By filling thread voids, it limits micro-movements and helps block capillary leak paths. It is specified for use on threaded connections up to M80 (R 3\u201d) and supports tolerance management with a maximum gap-bridging capability of 0.30 mm. With a high-viscosity range of 14,000\u201324,000 mPa\u00b7s, it offers an application behavior that reduces the risk of running, especially on vertical surfaces or wide thread profiles. The manufacturer is WEICON GmbH & Co. KG and the origin is Germany.<\/p>\n
Surfaces should be cleaned of oil, dirt, and loose oxides; a clean metal surface directly affects sealing and locking performance. The product should be applied evenly using the dispensing tip, taking care not to let the tip contact metal; not returning product that has contacted metal back into the bottle is critical to prevent premature curing inside the package. For sealing, the material is applied to the thread in circular movements, the parts are assembled, and the desired tightening is achieved. In serial production, using dosing equipment can be an advantage for repeatability and process control. This discipline helps keep results stable in anaerobic sealing approaches based on industrial adhesives used instead of tapes or pastes.<\/p>\n
AN 302-75 develops handling strength within 15\u201330 minutes, and full strength is expected to form within 3\u20136 hours; therefore, the loading plan should consider the first hours. Temperature resistance is stated as -60 \u00b0C to +150 \u00b0C, matching typical operating conditions in many plumbing and process lines. For threaded joints, breakaway torque and prevailing torque are both given as 40\u201350 Nm, supporting its high-strength locking character. Shear strength is reported as 15\u201325 N\/mm\u00b2 according to DIN 54452, serving as a reference for assemblies targeting permanent sealing. In pressure resistance evaluations using a set screw, performance limits up to high pressures are defined depending on the connection size; connection geometry and service conditions should be considered together in application design.<\/p>\n
The product supports a safety-oriented approach especially for pipe and thread sealing applications with an approval information stated under BAM DIN EN 1797. It helps reduce leak risk in points exposed to vibration and thermal change such as compressed-air installations, process lines, valve and fitting threads, and auxiliary connections of pumps and compressors. High viscosity improves application control, while green and fluorescent traceability makes visual verification easier in maintenance and quality control steps. It has a stated storage stability of at least 24 months at room temperature in its unopened original packaging and should be protected from heat sources and direct sunlight. In this way, AN 302-75 offers an industrial-adhesive-based sealing alternative that is compatible with process needs for businesses seeking permanent sealing in pipe and threaded connections.<\/p>\n","protected":false},"excerpt":{"rendered":"
