Product overviewOverview

This is static sealing for modest pressures and joints that are not opened often. Sealing follows the compression ratio, not the amount of sealant. Too little compression leaves a gap, too much takes a permanent set and stops recovering, so the installed thickness has to land inside a defined window and is verified by test rather than by inspection.

installed by threaded in, coating filling the clearance.

Key featuresFeatures

Compression ratio decides sealing, not sealant thickness.
Provides locking as well, so no separate locking element is needed.
Applied in production, so the assembly line needs no sealant and no cure wait.
Several sealant grades for coolants, oils and gases.

Typical applicationsApplications

Pneumatic end caps
Outdoor equipment junction cavities
Engine and gearbox housing threads

Selection notesSelection

Do not solvent-clean the thread before assembly; residue interferes with adhesion.

Frequently asked questionsFAQ

Is a thicker sealant layer better?

No. A thick layer may not compress enough and a thin one is crushed, and both leak. The installed thickness is controlled to the compression ratio the sealant was designed for.

What matters during installation of the IP68 Pre-applied Adhesive Sealing Bolt1?

Thread it in so the coating fills the thread clearance. Compression ratio decides sealing, not sealant thickness.

Manufacturing and inspection

Coverage and thickness are checked microscopically, with gauging to confirm the coating does not block the thread.We recommend a pilot assembly at the actual torque and mating part before locking the process parameters for volume.
