Description
Hydraulic Sealant 35S42 - Arexons
Specific product for sealing threaded joints in hydraulic and pneumatic pipelines up to 3/4" diameter.
Removal is possible with normal tools.
Product with medium thixotropy and medium mechanical strength.
The thixotropic property prevents the treated surfaces from dripping and allows application without waste. Medium mechanical resistance makes disassembly possible.
Ensures a perfect seal against liquids and gases.
Forms a tenacious film that increases the structural strength of the joint.
Protects threads against corrosion and prevents loosening caused by vibration.
It does not clog micro-passages and does not contaminate hydraulic or pneumatic circuits.
The anaerobic characteristic, i.e. fluid state in the presence of air, allows easy removal of excess product.
For faster sealing, we recommend System AP724 Rapid Primer.
Employment
Recommended for sealing threaded joints and fittings in general, pipes and vessels containing gas, LPG, compressed air, oil and fuels, industrial fluids, CFCs, drinking water and various chemicals.
