Peanut Fitting





The A/C condenser core and the connection between the receiver drier manifold assembly (outlet) and the TXV manifold and tube assembly (inlet) use the peanut-shaped refrigerant fittings instead of spring lock couplings.
- 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.
- The female block is welded to the tube and is not adjustable.
- Support the female fitting with a wrench to prevent the twisting of tubes.
- The male block will pivot around the tube to allow for alignment with the female block during assembly
- When correctly assembled, the male and female fittings should be flush.
