Whirlpool Refrigerator Compressor Replacement Requires This Fitting — 8mm Brass Connector W11506619
The W11506619 is the OEM 8mm straight brass connector required when replacing the compressor in compatible Whirlpool and KitchenAid refrigerators. In Whirlpool-platform refrigerators using the W11370574 compressor kit, this fitting connects refrigerant lines at the compressor — old fittings must never be reused, as a compromised brass connector will cause a refrigerant leak at the connection point and require the entire sealed system repair to be repeated. ⚡ Required installation fitting — do not reuse old connectors. Part W11506619 is the genuine OEM replacement, superseding W10891056 and W10896690, sold individually.

⚙️ Installation
Skill Level: Advanced — Professional installation required. This fitting is used during compressor replacement, which involves working with the sealed refrigerant system — EPA Section 608 certification (or equivalent in Canada) is required to legally handle refrigerants. Evacuate the system before opening any refrigerant lines. Install the new W11506619 connector, torque to manufacturer specifications, and leak-test all connections before recharging. Never reuse old brass fittings.

💡 Pro Tip
Brass refrigerant connectors are single-use components — once removed, the sealing surfaces are compromised and the fitting cannot reliably hold refrigerant pressure. A reused fitting that leaks after recharge means evacuating and recharging the system again, doubling your labour cost. At under $20, W11506619 is the cheapest insurance in a compressor replacement job.
