Replacing a GE Monogram or Café Refrigerator Compressor? Lokring WG03A03316 – Reconnect Refrigerant Lines Without Soldering

If you are replacing the compressor on a GE Monogram, Café, or Profile refrigerator, the WG03A03316 Lokring is the factory-specified fitting required to reconnect the refrigerant lines at the 10.5MM × 8MM connection point. In most GE refrigerators, Lokring press-fit couplings are the OEM method for joining copper refrigerant tubing without soldering — they are single-use fittings that form a permanent, leak-free mechanical seal when pressed with the correct tooling. Without the correct Lokring size, the refrigerant circuit cannot be properly sealed and the new compressor will fail to hold charge. ⚡ Required consumable on GE Monogram ZIS, ZISS, ZISB, ZIF, ZIR, Café CSB, CWE, CYE, CFE, and Profile GWE, GYE, PYD compressor replacement jobs. Part WG03A03316 is the genuine OEM 10.5MM × 8MM Lokring that replaces WR97X33345 and L13000702 and seals the refrigerant circuit correctly on the first press.

❓ Is This the Right Part?

This is the correct fitting if ALL of the following are true:

• ✔ You are performing a compressor replacement on a compatible GE Monogram, Café, or Profile refrigerator
• ✔ The connection point requiring this Lokring is confirmed as 10.5MM × 8MM — verify before cutting
• ✔ Refrigerant has been fully recovered by a certified technician before any line is cut
• ✔ Lokring press tooling with 10.5MM jaw is available on-site
• ✔ ONLY fitting needed is the 10.5MM × 8MM size — confirm all connection point sizes before ordering

🔧 Common Situations Requiring This Part

• Compressor replacement on compatible GE Monogram, Café, or Profile refrigerator — most common use
• Refrigerant line disconnected or cut during service
• Refrigerant leak confirmed at a line joint on a compatible model
• Previous Lokring damaged, improperly pressed, or leaking after prior service
• Refrigerator not holding refrigerant charge after compressor replacement
• New compressor installed but system won’t hold vacuum — leak at line coupling

✔ If this situation matches, WG03A03316 is the correct 10.5MM × 8MM Lokring for the job.

✔ A correctly pressed Lokring forms a permanent, leak-free seal that does not require re-torquing or follow-up service.

📦 Part Details

• Part Number: WG03A03316
• Type: Compressor Lokring — 10.5MM × 8MM single-use press-fit refrigerant line coupling
• Replaces: WR97X33345, L13000702 (no modification required)
• Brands: GE Monogram, GE Café, GE Profile (GE-platform refrigerators)
• Tooling Required: Lokring press tool with 10.5MM jaw (not included) — single-use, do not reuse after pressing

⚙️ Installation

Skill Level: Professional Only — EPA certification and Lokring press tooling required. Fully recover all refrigerant before disconnecting any lines. Cut the refrigerant line cleanly and deburr the end — the tube must be round, clean, and free of burrs for the Lokring to seal properly. Slide the WG03A03316 Lokring onto the tube end, insert the tube to full depth, and press with the correct 10.5MM Lokring jaw until the tool clicks or bottoms out. After recharging, leak-test all Lokring connections with an electronic leak detector before returning the unit to service. Never attempt to reuse a pressed Lokring — a single-use fitting that has been pressed cannot form a reliable seal a second time.
