With the Loctite si 5331 thread sealant in a practical 100 ml tube, you create flexible, leakproof joints in hot and cold water installations. This liquid silicone sealant is engineered specifically for plastic threaded fittings and plastic-to-metal combinations, preventing leaks without damaging fragile threads during assembly. It cures at room temperature with atmospheric moisture, delivering immediate sealing against low water pressure. Approved for potable water under dvgw (EN 751-1) and wrc (BS 6920) standards, it is suitable for sanitary, drainage, and irrigation pipe systems. Its low-strength formulation protects connections against vibration-induced loosening while allowing effortless disassembly with standard hand tools whenever maintenance is required.
