Description
Gas and liquid sealant 35A77 100ml - Arexons 4726
Specific product for sealing threaded joints and fittings in general, of pipes and vessels containing gas, LPG, compressed air, oil and fuels, industrial fluids, CFCs, drinking water and various chemicals.
Suitable for diameters up to 2". Resistant to shock and vibration and retains its sealing properties in the temperature range from -55°C to +150°C with peaks for short periods up to 230°C (24h to +230°C on 1 ½" galvanised fittings).
The high thixotropy prevents the treated surfaces from dripping and allows application without waste.
Guarantees a perfect seal.
Protects threads against corrosion and prevents loosening caused by vibration.
Does not create obstructions in micro-passages and does not contaminate hydraulic or pneumatic circuits.
Disassembly is possible with normal tools.
For faster sealing, we recommend the use of System AP 724 Primer Rapido.
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.
