LOCTITE 565
Harmonization Code : 3910.00.00.90 | Silicones in Primary Forms; Others
Main features
- Controlled-Locking Thread Sealing
- High-Pressure Pipe Sealability
- High-Viscosity Paste Application
Product Description
LOCTITE 565 is a controlled-torque anaerobic methacrylate paste for tapered metal pipe threads and fittings, combining high viscosity with low cured locking strength. The white to off-white material cures when confined between close-fitting metal surfaces. At 25 deg C, typical specific gravity is 1.1 and typical Brookfield RVF viscosity is 175,000 to 525,000 mPa s with spindle 7 at 2 rpm. In an ASTM D1599 pressure test, 3/8 in NPT steel pipe tees and plugs pre-torqued to 27 N m and cured for 24 hours maintained sealability at 207 bar (3000 psi). Typical breakaway torque after 72 hours at 22 deg C is 5 N m on 3/8 NPT steel pipe tees and plugs by ASTM D6396.
Key features
- Controlled locking strength: Low-strength anaerobic cure locks and seals close-fitting metal threaded connections.
- High-pressure sealability: 3/8 in NPT steel pipe assemblies cured for 24 hours were successfully sealed at 207 bar in an ASTM D1599 test.
- High-viscosity application: Typical Brookfield RVF viscosity is 175,000 to 525,000 mPa s at 25 deg C with spindle 7 at 2 rpm.
Applications
Locking and sealing tapered metal pipe threads and fittings.
