⚠️ Professional Installation Required. Lokring installation requires specialized Lokring press tooling and EPA-certified refrigerant handling. This part is sold for professional service use. Improper installation will result in refrigerant leaks and compressor failure.
Replacing a GE Refrigerator Compressor? Lokring WG03A03385 – Reconnect Refrigerant Lines Without Soldering
If you are replacing the compressor on a GE, Profile, or Monogram refrigerator, the WG03A03385 Lokring is the factory-specified fitting required to reconnect the refrigerant lines at the 8MM × 7MM 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, Profile, and Monogram compressor replacement jobs across GSS, GNE, GFE, GZS, ZIC, ZIK, ZIW, CYE, CWE, and CFE series platforms. Part WG03A03385 is the genuine OEM 8MM × 7MM Lokring that replaces WR97X31246 and L13000657 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, Profile, or Monogram refrigerator
- ✔ The connection point requiring this Lokring is confirmed as 8MM × 7MM — verify before cutting
- ✔ Refrigerant has been fully recovered by a certified technician before any line is cut
- ✔ Lokring press tooling with 8MM jaw is available on-site
- ✔ ONLY fitting needed is the 8MM × 7MM size — confirm all connection point sizes before ordering

🔧 Common Situations Requiring This Part
- Compressor replacement on compatible GE, Profile, or Monogram 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, WG03A03385 is the correct 8MM × 7MM 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: WG03A03385
- Type: Compressor Lokring — 8MM × 7MM single-use press-fit refrigerant line coupling
- Replaces: WR97X31246, L13000657 (no modification required)
- Brands: GE, GE Profile, GE Monogram, Haier (GE-platform refrigerators)
- Tooling Required: Lokring press tool with 8MM jaw (not included) — single-use, do not reuse after pressing
⚠️ GE Compressor Jobs Typically Require Multiple Lokring Sizes:
Most GE compressor replacements require two or three different Lokring sizes depending on the model — confirm all connection point sizes before recovering refrigerant. Once you cut the line, you’re committed. Having all required Lokrings on hand before starting eliminates a mid-job parts wait with the customer’s fridge down.

⚙️ 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 WG03A03385 Lokring onto the tube end, insert the tube to full depth, and press with the correct 8MM 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.

💡 Pro Tip
Confirm All Lokring Sizes Before You Recover Refrigerant:
GE compressor replacements typically require the 8MM × 7MM (WG03A03385), the 8.5MM × 6MM (WG03A03126), and sometimes the 10.5MM × 8MM (WG03A03316) — depending on the model and connection points. Confirm which sizes apply to each connection point on your specific model before recovering refrigerant. Once you cut the line, you’re committed — having all required Lokrings on hand before starting is the only way to avoid a mid-job parts wait with a customer’s fridge down.
