OEM vs. Generic

This genuine Goodman OEM seal and nut is dimensionally matched to the factory fitting, ensuring a reliable refrigerant-tight seal. Generic hardware-store nuts and washers are often the wrong thread pitch or seal durometer, leading to slow leaks and repeat service calls. For a fitting that holds system pressure, OEM is the safe choice.

Installation Difficulty

Intermediate. Replacing the seal and nut requires loosening the refrigerant connection (system recovery may be needed depending on access), seating the new seal, and torquing the nut to spec. Best handled by an EPA 608-certified technician. Allow 30–60 minutes.
