3M™ Scotch-Weld™ Hydraulic/Pneumatic Sealant is a purple, fast-curing, medium viscosity pipe sealant. Offering temperature resistance up to 300°F (149°C), this sealant provides a strong, tough seal that can be easily disassembled. This pipe sealant is also formulated to resist pressure and vibration for long-lasting durability.
3M™ Scotch-Weld™ Hydraulic/Pneumatic Sealant is a single-component, anaerobic sealant that cures and seals hydraulic and pneumatic pipes and fittings. This general-purpose, paste pipe sealant is fast-curing, sealing almost instantly, and withstands high temperatures and pressure. We also designed this sealant for disassembly, creating a strong, tough seal that can be later disassembled with ease. This sealant is formulated to resist pressure and vibration as well as to lock and seal medium to coarse straight and tapered threads. 3M™ Scotch-Weld™ Hydraulic/Pneumatic Sealant provides an almost instant low-pressure seal. A high-pressure seal results when the bond is fully cured. It seals quickly to stop leaks when applied to threads or compression fittings of most metal and certain plastic pipes, without shredding, evaporation, or shrinkage. In addition, this sealant prevents galling as well as helps eliminate the waste and mess of leaking hydraulic fluids, oil, fuel, and lubricants. Offering a rapid seal that withstands heat, pressure, and vibration, 3M™ Scotch-Weld™ Hydraulic/Pneumatic Sealant is an excellent solution for fast results. Resilient and durable, this pipe sealant is formulated to produce the strong seal necessary for a wide variety of demanding applications.
