Peanut Fitting
WARNING: This page is about a different car, the 2004 Mercury Monterey and 2004 Ford Freestar. However, it is still accessible from the selected car via links, so may be relevant.
The A/C refrigerant line peanut fittings are sometimes used in place of spring lock couplings or tube-o fittings.
- The male and female blocks of the peanut fitting are retained with a nut.
- An O-ring seal is installed around the tube on the male block.
- Support the female fitting with a wrench to prevent twisting of the tubes.
- When correctly assembled the male and female fittings should be flush.
