LG Refrigerator Pipe,Compressor Sealing

The LG Refrigerator Compressor Process Tube (Part Number: 4J00977P) is an authentic original equipment manufacturer (OEM) replacement copper component designed for LG refrigeration systems. Attached directly to the compressor housing process port, this pre-bent copper stub tube allows certified technicians to evacuate, vacuum test, and recharge the sealed refrigeration system with refrigerant during compressor replacements or leak repairs.

Key Features

• High-Purity Seamless Copper: Manufactured from heavy-wall, refrigeration-grade copper to withstand high operating pressures and temperature cycles.

• Pre-Bent Factory Contour: Formed with a precise slight curvature to facilitate clean torch clearance and hassle-free brazing in tight compressor bays.

• Corrosion & Leak Resistant: Provides excellent ductility for clean swaging, pinch-off sealing, and leak-free sweat connections.

Benefits

• Facilitates smooth refrigerant charging and pressure testing during sealed system repairs.

• Maintains proper sealed-system integrity to ensure long-term cooling efficiency and compressor health.

• Direct OEM replacement ensures precise wall thickness and outer diameter for standard service access valves.

Applications

Designed specifically for select LG refrigerator sealed systems requiring part number 4J00977P.

What's Included

• 1 x Genuine LG Refrigerator Compressor Copper Process Tube (4J00977P)

Usage Instructions

1. DANGER: Sealed system repairs require EPA certification, specialized brazing equipment, and proper refrigerant recovery practices.

2. Recover existing refrigerant from the system following safety regulations.

3. Desolder or cut the old process stub tube from the compressor port.

4. Clean and prep the compressor port surface with emery cloth.

5. Insert the new LG 4J00977P copper tube into the port and braze using silver solder alloy.

6. Attach a piercing or access valve, pull a deep vacuum, recharge with factory-specified refrigerant, and crimp/seal the process tube end.

Safety Instructions

• Sealed system service must be performed by an EPA-certified HVAC/R technician.

• Wear protective safety goggles and heat-resistant welding gloves during torch brazing operations.

Care Instructions

• Ensure copper ends remain clean, dry, and capped prior to brazing to prevent moisture contamination inside the sealed system.
