The Goodman B1796632 Seal and Nut (3/8 inch) is a genuine OEM sealing kit used at the 3/8 in. flowrator and refrigerant tube connection on ARPF36421BA air handlers.

OEM vs. Generic

The genuine Goodman OEM seal is molded to the exact durometer and dimensions of the original, paired with a correctly threaded nut. Generic O-rings and hardware can extrude, crack, or cross-thread under refrigerant pressure, causing slow leaks that drain the charge. OEM hardware guarantees a proper seat and torque.

Install Difficulty

Intermediate — straightforward for an HVAC technician at an open joint, but it sits on the sealed refrigerant circuit, so refrigerant must be recovered before opening the connection. Replace the seal any time the joint is broken, lubricate per spec, and torque the nut to manufacturer values. EPA 608 certification required.
