SFC Koenig has announced a project with a major OEM to develop seals for new anti-lock brake and traction control systems. The designer identified the need for a superior solution to seal central manifold ports after the original ball plug sealed holes created debris during the press-in installation, as well as having a high rate of seal failures.
“Seal performance was critical to the successful operation of this new system, and selection was made more complex due to the anodized aluminum manifold base material,” said Nate Moore, product manager at SFC Koenig.
“Installation of the existing ball plug seals was resulting in cracks and leaks. Our team worked with the customer’s engineering department to identify the best sealing components and installation equipment to provide reliability, safety and performance, while easily integrating into their high-speed production environment.”
The Koenig Expander MB 850-040E was chosen based on size requirements, materials, pressures, installation processes and the overall safety-critical nature of the application. The company developed an expansion design to combat previous issues. When inserted, the plug’s serrated sleeve was expanded into the base material and formed a reliable seal that required no sealant or additional machining.
During the selection, SFC Koenig’s engineers gave special consideration to ensure the anodized aluminum base would not wear during repeated thermal and pressure cycles. “The combination of our MB 850 and our installation equipment reduced the risk of contamination, streamlined seal installation, and in the long run has lowered their costs when warranty and rework expenses are considered.”
