OEM Goodman Liquid Line Cap w/ O-Ring for WAHME3137P4AAA — B9102097

Goodman B9102097 Liquid Line Cap with O-Ring

The Goodman B9102097 is a genuine OEM liquid line cap supplied with its sealing O-ring, designed as a direct replacement for the WAHME3137P4AAA air handler. The cap threads onto the liquid line service fitting and, together with the O-ring, forms a secondary leak-tight seal that protects the refrigerant charge and keeps moisture and contaminants out of the system. A missing or damaged cap—or a dried, cracked O-ring—can allow slow refrigerant loss and is an easy, inexpensive item to replace during any service call.

OEM vs. Generic

The genuine Goodman OEM cap arrives with the correctly sized O-ring already matched to the fitting, so it seats flush and seals on the first turn. Generic caps are often sold without an O-ring or with an incorrectly sized one, which leads to weeping joints and repeat leaks. For a part this critical to charge integrity and this affordable, OEM is the clear choice.

Installation Difficulty

Easy. Verify the system is not under access pressure, seat the O-ring, hand-thread the cap, and snug it to spec—typically a 5-minute job. No special tools required, though a torque-aware approach prevents over-tightening and O-ring damage.
