Is the PUSH-IN straight coupling for hose, brass, type AI 58040 compatible with polyamide lubrication hoses and safe at temperatures from -30Â°C to +150Â°C?

Yes. The PUSH-IN straight coupling for hose, brass, type AI 58040 is specified for use in lubrication technology and the recommended hose material is polyamide, so it is compatible with polyamide lubrication hoses. Its body is nickel-plated brass with an HNBR oâring seal and the operating temperature range is listed as â30Â°C to +150Â°C, so it is safe to use within that temperature range. Note the maximum working pressure: 150 bar for liquids and 30 bar for air; ensure your application stays within these limits.

Can the PUSH-IN straight coupling for hose, brass, type AI 58040 handle 150 bar liquid pressure and 30 bar air pressure safely?

Yes. The PUSH-IN straight coupling for hose, brass, type AI 58040 is rated for a maximum working pressure of 150 bar for liquids and 30 bar for air, so it can safely handle 150 bar liquid pressure and 30 bar air pressure when used within the specified conditions. Ensure connected hoses are polyamide (as recommended), the temperature stays within -30Â°C to +150Â°C, fittings are properly installed, and Oâring (HNBR) compatibility with the fluid is verified.

Does the PUSH-IN straight coupling for hose, brass, type AI 58040 use HNBR O-rings suitable for lubrication fluids?

Yes. The PUSH-IN straight coupling for hose, brass, type AI 58040 uses an HNBR O-ring as the sealing material. HNBR (hydrogenated nitrile butadiene rubber) is commonly suitable for many lubrication fluids (oils and greases) within its compatibility range. Given the productâs stated operating temperature range (â30Â°C to +150Â°C) and maximum liquid pressure (150 bar), the HNBR O-ring specified for this coupling is appropriate for typical lubrication technology applications. Always verify compatibility with the specific lubricant and operating conditions (temperature, pressure, additives) used in your system.
