High-quality rubber pressure hose manufactured in the USA with an inner layer made of chemically resistant polyamide (nylon). The very smooth inner surface reduces flow losses and ensures ease of cleaning. Reinforcement with synthetic textile braiding provides high pressure resistance and low deformation under pressure. The smooth outer layer made of synthetic rubber is resistant to contact with chemicals and oil (RMA Class B – medium resistance). For hoses with an inner diameter of 1/4″ and 3/8″, the outer layer is antistatic R<10⁶Ω. The hose is intended for industrial applications, particularly for organic solvents and petrochemical substances. The good resistance of polyamide to many solvents allows the hose to be used in the paint industry for the transfer of paints, varnishes, adhesives, and resins. Chemical resistance and potential static electricity issues must always be considered. In particular, antistatic hoses with diameters of 1/4″ and 3/8″ are widely used as pressure feed hoses for spray guns in automotive workshops, construction, and industry. Chemical resistance verification: chemical resistance table for PA (preliminary selection), confirmation of resistance and application conditions by Tubes International. Installation: smooth fittings with a spigot (“tail” for the hose) without sharp or high ribs that could cut or damage the inner polyamide layer when tightened should be used. Typical hydraulic fittings can be used. The spigot diameter should be precisely matched to the hose diameter to ensure sealing. Installation depending on working pressure with hose clamps, crimp fittings, or for larger diameters with shell clamps. Typical factory hoses for spray guns often have reusable screw fittings. Inner layer: polyamide (PA), silicone-free. Reinforcement: single textile braid for 1/4″ and 3/8″, double for 1/2″. Outer layer: black synthetic rubber. Working pressure: 52 bar. Operating temperature: from -20°C to +90°C.
