Parker XTR fittings fight corrosion

New XTR (Extreme Resistance) coated hose and tube fittings from Parker Hannifin Corporation provide corrosion protection for mobile and industrial applications that come into contact with nitrogen-based fertilizers and other harsh chemicals or environmental elements.

Using new XTR coating, users can avoid the potential costs of corrosion damage, including hydraulic system leakage, replacement of fittings, increased warranty costs due to labor, and potential lost sales due to poor product perception.

In applications where nitrogen-based fertilizers are used or caustic environments are encountered, standard hose and tube fittings can become severely corroded in as little as 14 days.

In a recent ASTM B117 Salt Spray Test, Parker's XTR-coated fittings provided standard level corrosion resistance for more than 720 hours — more than seven times the SAE requirement of 96 hours.

The new hose and tube fittings are also ideal for combating corrosion on mobile applications subjected to severe environmental conditions. OEM customers can benefit from using the new fittings as they can gain plant space and increased throughput by potentially eliminating the need for secondary paint lines. Machines and equipment designed with XTR-coated fittings are better protected against corrosion during shipment, thus preserving their factory-new appearance.

XTR-coated fittings comply with:

  • SAE J514 and J1453

  • “Restrictions of Hazardous Substances” — Directive 2002/95/EG (RoHS)

  • “End of Life Vehicle” — Directive 2000/53/EG (ELV)

  • “Registration, Evaluation, and Authorization of Chemicals” (REACH)
