The Goodman B1796632 Seal and Nut (3/8") is a genuine OEM sealing kit for the ARPF363616AA air handler. This 3/8-inch fitting set provides a leak-tight refrigerant or condensate connection at the coil, pairing a precision-molded seal with the matched compression nut so the joint holds pressure without weeping. Old, hardened, or deformed seals are a common cause of slow refrigerant loss and nuisance service calls — fresh OEM hardware restores a positive seal the first time.
The genuine OEM seal and nut are machined to Goodman's exact thread pitch and seat profile. Generic replacements often differ slightly in durometer or bore, leading to over-torque, cracked seals, and repeat leaks. This factory kit guarantees correct sealing on the first install.
Easy (2/5) — Hand tools only. Verify system is depressurized, seat the seal, and torque the nut to spec. Most techs complete this in under 10 minutes.
