LOCTITE 638 - Thread Sealant for Hydrogen Application

LOCTITE 638 is a green, medium viscosity, fast anaerobic curing adhesive with high shear strength.

Typically used to retain bearings on shafts and other cylindrical assemblies, but it is also ideal for thread sealing and threadlocking applications exposed to high pressure and/or extreme condition environments.

Ideal for BSPT and NPT pipe threads.

The product has been deemed hydrogen ready for use on metal fittings only, according to GASTEC QA AR 214. Class 8.

Key features

Desinged for bonding for shafts, gears, pulleys and similar cylindrical parts.

Also ideal for thread sealing and threadlocking applications exposed to high pressures or extreme environments.

Hydrogen ready for use on metal fittings according to GASTEC QA AR 214. Class 8.

DVGW Approval (EN 751-1): NG-5146AR0619.
