LOCTITE® 510 High Temperature Gasket Sealant
Known as Loctite 510 Gasket Eliminator Flange Sealant
Features and Benefits
Available sizes:
This form-in-place anaerobic-curing gasketing sealant provides high temperature and chemical resistance on close fitting, rigid machined metal flanges.
LOCTITE® 510 is a high-temperature resistant, form-in-place anaerobic-curing sealant, which forms an instant, low-pressure seal when confined in the absence of air between close fitting metal surfaces. Ideal for rigid flanges, especially in transmissions and motor casings. Unprimed gap-fill is 0.25mm. Recommended for use with aluminum and steel substrates.
- For close fitting, rigid metal flanges
- Withstands temperatures to 400°F (204°C)
- Adapts to surface irregularities and scratches up to 0.010in (0.25mm)
- Increases the torque capacity of assembled flanges
- Registered to NSF Category P1

How to
Step by Step Guide
1. Preparation - Cleaning
For gasket repair applications only: Apply LOCTITE® SF 790™ to old gasket or gasket sealants and use a wood or plastic scraper to remove residues from flange surfaces. Remove burrs. It is recommended to use LOCTITE® SF 7070™ to degrease and clean surfaces prior to applying the sealant. For serial production make sure that surfaces are free of contaminations.
2. Preparation - Activation
If cure speed of LOCTITE® 510™ is too slow due to passive metals or low temperature (below 5°C), use LOCTITE® SF 7649™ activator. Allow to dry.
3. Application
Apply a continuous bead of sealant onto one flange surface. Place the bead close to the inner rim of the flange and encircle all bolt holes. Small surface scratches will be filled by the adhesive. LOCTITE® 510™ can also be applied by roller onto larger flanges.
4. Assembly
Assemble flanges and tighten bolts as soon as possible. Wipe away any excess squeeze-out, as this will not cure when exposed to air due to the sealant's anaerobic curing properties.
5. Disassembly
Disassemble bolts with standard hand tools. Use jacking-screws, cast-on bosses or recesses to lift flanges apart. Once disassembled, apply LOCTITE® SF 790 on old sealant and use a wood or plastic scraper to remove residues from flange surfaces.
