Is the NiTO 1/2" water quick connector set, brass safe to use with hot water up to +80Â°C and pressure up to 25 bar?

Yes. The NiTO 1/2" water quick connector set, brass is rated for use with hot water up to +80Â°C and for working pressure up to 25 bar. Its body is chrome-plated brass and the sealing material is NBR (nitrile), which is suitable for water but not for gasoline or oils. Ensure system compatibility with NBR (temperature and chemical exposure) and follow proper installation and maintenance practices to maintain safe operation within those limits.

Can the NBR seals in the NiTO 1/2" water quick connector set, brass be replaced for compatibility with oils or gasoline?

No. The NiTO 1/2" water quick connector set, brass uses NBR seals and the product description explicitly states they are not suitable for gasoline and oils. Replacing NBR seals with an oil- or gasoline-compatible elastomer (e.g., FKM/Viton, PTFE) would require compatible seal dimensions, hardness and a secure fit; however, compatibility with the chrome-plated brass housings, thread tolerances and pressure/temperature ratings (up to 25 bar, +80Â°C) must be verified. Because quick-connect designs are safety-critical and replacement seals may not be available from the manufacturer, modifying the set risks leaks, swelling or failure. Recommended: use a coupling specifically specified for fuels or contact the manufacturer for approved replacement seals rated for oils/gasoline.

Does the NiTO 1/2" water quick connector set, brass resist corrosion in chlorinated tap water?

Yes. the NiTO 1/2" water quick connector set, brass is suitable for use in chlorinated tap water. Reasoning from the product description: - The connectors are made of chrome-plated brass. Brass is commonly used for potable water fittings because it resists corrosion in typical municipal (chlorinated) water. Chrome plating adds an extra protective surface layer that improves wear resistance and helps prevent dezincification and surface corrosion. - The seals are NBR (nitrile rubber), which is compatible with chlorinated tap water and standard disinfectants used in drinking water systems (NBR is widely used for water service; it is only flagged as not suitable for gasoline and oils). - The specified working pressure (up to 25 bar) and operating temperature (up to +80Â°C) are well within normal tap-water conditions, so the material and seals will perform under typical household and commercial water supply parameters. Notes and caveats: - Extremely aggressive or unusually high-concentration disinfectants (strong oxidizers beyond typical municipal chlorination) could accelerate wear on metals and elastomers; for such specialized chemical exposure, verify chemical compatibility. - Long-term corrosion resistance also depends on water chemistry (pH, chloride content, temperature) and installation conditions (electrolytic corrosion from dissimilar metals, stray currents). In normal chlorinated tap water environments, chrome-plated brass with NBR seals is appropriate and expected to resist corrosion. Conclusion: For standard chlorinated tap water, the NiTO 1/2" water quick connector set, brass is corrosion-resistant and suitable for use.
