XTR (extreme resistance) coated hose and tube fittings from Parker Hannifin provide corrosion protection for mobile and industrial applications exposed to contact with nitrogen-based fertilizers and other harsh chemicals or environmental elements. The coating prevents corrosion damage and subsequent loss, including hydraulic system leakage and fittings replacement. In applications where nitrogen-based fertilizers are used or where caustic environments are encountered, standard hose and tube fittings can become corroded in as little as 14 days. In salt spray testing, certified XTR-coated fittings provided standard level corrosion resistance for more than 720 h—more than seven times the SAE requirement of 96 h.
