A Pull Anchor Expander Plug is used to create a reliable seal between mating surfaces within the transmission case. The grooves create additional contact points between the sealing plug and the mating surfaces, improving the sealing efficiency. When the plug is tightened, the grooves compress against the mating surfaces, creating a tight and secure seal.Attributes:• Manufactured with precise specifications to fit accurately• Helps to maintain the integrity and reliability of the transmission unit partsApplications:A Pull Anchor Expander Plug acts as a barrier or sealant to prevent fluid leakage and the entry of contaminants into the transmission case parts.
