PARKER Hannifin Corporation’s Tube Fittings Division (TFD) has released a range of fittings designed to stop hydraulic systems leaking.
According to the company, the fittings provide leak-free capabilities and protect against red dust and corrosion due to their high-quality platings.
The fittings are designed to withstand harsh operating environments, particularly those that promote the onset of red rust due to the formation of iron oxide, which signals oxidation and deterioration of the fitting base metal.
In a recent salt spray test conducted by an independent test center, Parker TFD fittings remained free of red rust after 480 hours exposure, the company claims. This result is said to exceed both the current SAE requirement of 72 hours, and proposed new SAE requirement of 96 hours.
According to Parker, its TFD fittings and fittings from five major competitors were exposed to a neutral salt spray test ASTM B117. All of the competitors’ fittings reportedly exhibited red rust after 240 hours, with the exception of the Parker fittings. It is possible that, in real-world applications, replacement of these competitor fittings would be necessary, the company says.
