Main features
- Particle-Free Hydraulic Sealing
- Large-Diameter Thread Coverage
- Hand-Tool Fitting Disassembly
Product Description
LOCTITE 5452 is a one-part, purple methacrylate ester thread sealant for hydraulic and pneumatic fittings. The medium-viscosity, thixotropic liquid cures anaerobically when confined between close-fitting metal threads. It is formulated without fillers or particles that could interfere with hydraulic systems and is suited to tapered and large-diameter pipe, dry-seal, O-ring boss, and flare-style fittings. On flare fittings, the sealant can cover scratches and surface imperfections on mating faces. Cured fittings can normally be disassembled with standard hand tools, with mechanical cleaning before reuse.
Key features
- Particle-free formulation: Contains no fillers or particles that could interfere with a hydraulic system.
- Multiple fitting geometries: Applies to tapered pipe, dry-seal, O-ring boss, and flare-style fittings.
- Anaerobic metal-thread cure: Cures when confined without air between close-fitting metal threads.
Applications
Applications include sealing hydraulic and pneumatic threaded fittings, including tapered and large-diameter pipe, dry-seal, O-ring boss, and flare fittings.
