OEM Goodman Liquid Line Cap with O-Ring for WGHP4448AAF — B9102097

The Goodman B9102097 Liquid Line Cap is a genuine OEM refrigerant service-port seal engineered for WGHP4448AAF packaged units and compatible Goodman/Amana air conditioner and heat pump systems. It threads onto the liquid line service port to provide a leak-tight cap-and-O-ring seal that protects the charge and keeps moisture and debris out of the sealed refrigerant circuit.

Unlike a generic brass cap, this part ships with the correctly durometer-rated O-ring already fitted, so you get a positive metal-to-metal plus elastomer seal on the first turn — critical for holding R-410A pressures without slow leaks.

• Part type: Liquid line service cap with O-ring
• Fits: Goodman WGHP4448AAF and compatible package units
• Seal: Captive O-ring, refrigerant-rated
• Material: Plated brass body
• Service: Reusable; replace O-ring if nicked

OEM vs. Generic: Generic caps are often sold without the matched O-ring or with a Buna ring that hardens under R-410A exposure, leading to weeping service ports. This OEM B9102097 is built to Goodman's original spec for guaranteed fit and a reliable long-term seal.

Install difficulty: Easy (1/5). Hand-tighten then snug with a wrench after the system is charged and leak-checked. No special tools required. Always recover refrigerant and follow EPA Section 608 practices if the port is opened under pressure.

Backed by Goodman OEM quality for dependable refrigerant containment on your WGHP-series equipment.
