Can SYNFLEX 1300 Polyethylene-Aluminum Air Hose be installed underground without additional protective coverings?

Yes. SYNFLEX 1300 Polyethylene-Aluminum Air Hose can be installed underground without additional protective coverings. Its construction—inner polyethylene layer, aluminum reinforcement, and outer black polyethylene—provides the strength, chemical resistance, and durability required for direct-burial applications. The hose’s ability to span long sections without extra supports, combined with its shape memory for easy routing in confined spaces and wide operating temperature range (-40°C to +80°C), further supports underground use. Ensure installation follows local regulations and site-specific requirements (e.g., depth, backfill material, and mechanical protection where required by code).

Is SYNFLEX 1300 Polyethylene-Aluminum Air Hose suitable for use in corrosive chemical environments and which chemicals should be avoided?

SYNFLEX 1300 Polyethylene-Aluminum Air Hose offers good resistance to many corrosive environments thanks to its outer polyethylene layer, which is noted for chemical resistance, and its aluminum reinforcement that provides structural strength. It is therefore suitable for many aggressive industrial atmospheres and can be used underground and in confined spaces. However, limitations apply. Avoid prolonged contact with strong oxidizing agents (e.g., concentrated nitric acid, perchloric acid, and strong bleaching agents) that can attack polyethylene or promote corrosion of metal components. Highly chlorinated solvents, aromatic hydrocarbons (e.g., toluene, xylene), and strong acids or bases at elevated temperatures or concentrations may degrade polyethylene or affect seals and fittings. Also avoid exposure to molten metals or open flames beyond the hose’s +80°C limit. For any specific chemical, concentration and temperature, verify compatibility with manufacturer chemical-resistance data and test under actual service conditions; where risky chemicals are present, use specialized chemical-resistant hoses or additional protective barriers.

The polyethylene and aluminum pneumatic hose is a high-performance solution designed for advanced pneumatic control systems, combining durability, flexibility, and reliability in one product. Its inner polyethylene layer ensures smooth airflow, while the aluminum reinforcement significantly strengthens the structure, allowing the installation of long sections without the need for additional supports. The outer black polyethylene layer provides excellent resistance to chemicals, making the hose ideal for use in aggressive industrial environments. Thanks to its unique shape memory, it can be easily installed even in confined or hard-to-reach spaces, and its construction enables underground installation without extra protective coverings. Remarkably lightweight—up to five times lighter than standard pneumatic hoses—it offers easier handling, reduced installation time, and lower transportation costs. With a working pressure range of 20 to 28.8 bar, depending on diameter, and an impressive operating temperature span from -40°C to +80°C, this hose guarantees reliable performance in demanding conditions, making it a versatile and cost-effective choice for modern pneumatic systems.
