Superior plating gives fittings from Parker Hannifin Corporation’s Tube Fittings Division (TFD) protection against red rust, the company claims.
According to Parker Hannifin, this helps customers avoid the many costs of corrosion – calculated not only in terms of possible leak points and replacement fittings, but also potential lost sales stemming from poor product perception.
Parker TFD fittings can be used to gain a leak-free, well-functioning hydraulic system, the company claims.
Parker TFD fittings are said to withstand the harshest operating environments, particularly those that promote the rapid onset of red rust.
Red rust – the formation of iron oxide – signals oxidation and deterioration of the fitting base metal. This can degrade the fitting and compromise its performance.
And although the presence of red rust does not necessitate that a fitting be replaced, it can quickly undermine a customer’s confidence in the integrity of the system or machine it is installed on, Parker Hannifin claims.
The company’s platings were recently tested in salt spray by Miami Valley Materials Testing Center, an accredited independent test centre. The Parker TFD fittings remained free of red rust after 480 hours exposure, the company says.
According to Parker Hannifin, this result exceeds both the current SAE requirement of 72 hours (and proposed new SAE requirement of 96 hours) salt spray with no red rust.
