GM 3/8 Push Connect Transmission or Differential Line Plug
Sold as a pair (2)
These plugs are designed specifically for the GM 3/8 (.375") push connect fittings found all over most GM vehicles. You'll find these on differential cooler lines, transmission cooler lines, fuel lines, in the radiator and possibly other places. We designed these to be a permanent solution for blocking these coolers off in the scenario where you've deleted the factory cooler or just want to plug them off while working on the vehicle to minimize spillage. At this time we only have the 3/8 versions.
