The Goodman B1796632 Seal and Nut (3/8") is a genuine OEM sealing fitting for Goodman/Amana ARUF018-00A-1A air handlers. This 3/8-inch seal-and-nut assembly creates a leak-tight connection at the refrigerant line set or flowrator joint, preventing refrigerant loss and maintaining system pressure. A failed or hardened seal is a common source of slow refrigerant leaks and reduced cooling capacity.

Specifications

Part Number: B1796632 (OEM Goodman)
Type: Seal and nut fitting
Size: 3/8 inch
Fits: ARUF018-00A-1A air handlers (1.5 ton / 18,000 BTU)
Function: Leak-proof refrigerant line connection
Equipment: Goodman / Amana air handler

OEM vs. Generic

This genuine OEM seal and nut is machined to the precise thread pitch and sealing profile Goodman specifies for the ARUF018. Off-brand seals may use slightly different durometer material or thread tolerances, leading to weeping joints and repeat service calls. The factory part guarantees a positive seal on the first install.

Installation Difficulty

Moderate (Professional recommended). Because it sits on the refrigerant side, replacing this seal typically requires recovering and recharging the system. The fitting itself installs in minutes, but EPA-certified handling of refrigerant is required. Hire a licensed HVAC technician unless the line set is already open.
