Categories: ,



Anaerobic thread sealant, developed to carry moderate shear forces to seal threaded couplings. The adhesive has a slow curing mechanism to allow adjustments in the position of the mounted devices during an extended period.



• A moderate and controlled torque tension.
• Thixotropy and high viscosity provide the adhesive with a good filling capacity.
• Suitable for threaded connections till 3” (DM80).
• Seals immediately under low pressure (< 5 kg/cm²).
• Allows repositioning the threaded connection during 30 minutes, even under low pressure (< 5 kg/cm²).
• Great resistance to: temperature, corrosion, vibrations, water, gas, oils, hydrocarbons and most chemicals.
• Easy to dismount with normal tools, even after some years.
• Does not run or drip off.
• Does not migrate after assembly.
• Not suitable for plastic connections.



Adhesive specially recommended for:
• Sealing and fixing of metallic, threaded couplings in hydraulic or pneumatic installations.
• Eliminates the use of yarn and PTFE-ribbons.


Best results are obtained on clean, dry and grease free surfaces. For best results, clean with CRC industrial Degreaser. In general, roughened surfaces give higher bond strengths than polished or ground surfaces.

Apply a bead of CRC Easy Seal around the last two threads of the coupling.Assemble and apply the needed pre-torque when applicable. The assembly can be put immediately under low pressure (< 5 kg/cm²). If repositioning is needed, this can be done under low pressure (< 5 kg/cm²) during 20 – 40 minutes after application. The functional curing time is obtained 1 – 3 hours later and full resistance can be expected 5 – 10 hours from application. When assembled, any possible excess adhesive can be removed with a dry cloth or tissue.

Clean cured product by tramping the part for 10 min. into CRC Super Gasket Remover. Flush with water and remove remnants with a nylon brush.
