Refrigerator Leaking or Ice Maker Not Working? L13000588 Lokring Brass Connector – Fix Refrigerant Line Failures Fast
If your refrigerator has a refrigerant or water line leak, or the ice maker has stopped working after a repair, a failed or improperly joined line connector is the most common cause. In most Whirlpool, Maytag, and KitchenAid refrigerators, the Lokring brass connector joins 6mm (1/4") refrigerant or water lines at key junctions in the sealed system. When the connection fails or was never properly seated, the result is refrigerant loss, warm temperatures, or a completely non-functional ice maker. ⚡ Common failure point in Whirlpool-platform French door and bottom-freezer refrigerators. Part L13000588 is the genuine OEM Lokring straight brass connector that creates a permanent, leak-free 6mm-to-6mm joint — no soldering required.
❓ Is This the Right Part?
This is the correct fix if ALL of the following are true:
- ✔ Refrigerator powers on and compressor runs
- ✔ You have confirmed a line leak or are performing a sealed system repair
- ✔ The line diameter at the repair point is 6mm (1/4")
- ✔ You are using Lokring press-fit tooling for installation
- ✔ ONLY problem is a leaking or disconnected 6mm refrigerant/water line junction

🔧 Common Symptoms
- Refrigerator not cooling — warm fridge and freezer compartments
- Ice maker stopped producing ice after a repair or service call
- Visible frost or oil residue near a line junction in the sealed system
- Refrigerant charge lost shortly after recharge
- Error codes related to temperature or sealed system faults
- Hissing or bubbling sound near the evaporator or compressor area
✔ If these symptoms match and you have confirmed a 6mm line leak, this connector is the correct repair component.
✔ In most cases, a properly installed Lokring connector restores a permanent, leak-free seal immediately.

Lokring connectors require the correct press-fit crimping tool for a proper seal — do not attempt to seat with pliers or generic tools. If you are repairing a refrigerant line, ensure you have the correct Lokring installation kit and a certified technician performs the refrigerant recharge.
⚙️ Installation
Skill Level: Advanced — 30–60 minutes (plus refrigerant recharge time if applicable). Disconnect power and recover any remaining refrigerant before cutting the line. Cut the line cleanly and squarely at the repair point, slide the Lokring connector over both ends, and press to seat using the correct Lokring crimping tool. No soldering, brazing, or heat required. Recharge the sealed system with the correct refrigerant type and quantity per the appliance data plate.
💡 Pro Tip
Lokring connectors are a single-use, permanent press-fit — once crimped, the joint cannot be undone. Measure twice and confirm line diameter before pressing. Keep a spare connector on hand if you are working on multiple line junctions in the same service call, as a mis-press requires cutting and starting fresh.
