ACDelco Transmission Fluid Cooler Pipe Fitting Seal O-Ring

The ACDelco Transmission Fluid Cooler Pipe Fitting Seal O-Ring is a replacement sealing ring for the fittings on automatic transmission fluid cooler lines. It helps keep transmission fluid inside the cooler line connections, and it is also called a trans cooler line O-ring, cooler pipe seal, or transmission cooler fitting seal.

Key Features:

• Designed to seal the connection between the transmission fluid cooler pipe and its fitting
• Flexible elastomer construction suited to transmission fluid and the heat of normal operation
• Helps prevent fluid seepage and pressure loss at the cooler line connection
• Backed by ACDelco, a long-standing General Motors parts brand known for OE-quality replacement parts

Replacing the O-ring whenever a cooler line fitting is disconnected helps restore a reliable seal. It also helps protect the transmission from low fluid levels caused by leaks. Choose the individual part number that matches your application.
