Peanut Fitting

WARNING: This page is about a different car, the 2009 Ford Mustang. However, it is still accessible from the selected car via links, so may be relevant.

When disconnecting or connecting peanut fittings, observe the following.

The male and female blocks of the peanut fitting are retained with a nut.
Support the female fitting with a wrench to prevent twisting of the tubes.
An O-ring seal is installed around the tube on the male block.
On 4.6L and 5.4L vehicles, a gasket seal is installed along with the O-ring seal at the A/C compressor fittings.
When correctly assembled, the male and female fittings should be flush.
Use only the seals listed in the Ford Master Parts Catalog.
