A proprietary plating gives hydraulic fittings protection against red rust. This helps users avoid the cost of corrosion which is calculated in terms of possible leak points and replacement fittings, along with potential lost sales stemming
- Parker TFD fittings and those from five major competitors were exposed to neutral salt spray test ASTM B117. One competing fitting showed red rust upon reaching the current SAE requirement of 72 hours while two other fittings exhibited red rust upon reaching the 96 hours benchmark, thus falling short of the proposed new requirement. The two remaining competitor fittings showed red rust after 240 hours. It is possible that in real-world applications, replacement of some or all of these fittings would be necessary, with the exception of the Parker TFD fittings.
from poor product perception. The TFD fittings, from Parker Hannifin Corporation’s Tube Fittings Division (TFD), could be part of any leak-free, well-functioning hydraulic system.
TFD fittings withstand harsh operating environments, particularly those that promote the rapid onset of red rust. Iron oxide signals oxidation and deterioration of the fitting base metal, which can degrade the fitting and compromise performance. Although the presence of red rust does not necessitate replacing a fitting, it can undermine users confidence in the integrity of the equipment on which it is installed.
In a recent salt spray test conducted by an independent test facility, the Miami Valley Materials Testing Center, TFD fittings remained free of red rust after 480 hours exposure. This significantly exceeds both the current SAE requirement of 72 hours and the proposed new SAE requirement of 96 hours of salt spray without red rust.
