LG Washing Machine Bellows

Maintain leak-free washing operations and optimal tub pressure regulation with the authentic LG Washing Machine Vent Hose With Bellow (Part No: 4738ER2002A). Serving as an essential air pressure and water overflow relief conduit in compatible LG front-loading washing machines, this original rubber bellows hose channels internal air displacement between the outer washing tub and the rear cabinet vent frame.

Whether your washer's current vent hose has dry-rotted, torn from tub spin vibrations, clogged with detergent buildup, or developed water leaks around the spring clamp connections, this factory OEM replacement part restores a tight seal and smooth airflow.

Key Features

• 100% Genuine LG Component: Designed directly to original factory specifications for precise barb diameter fitment and sealed hose clamp seating.

• Flexible Bellow Accordion Section: Absorb severe tub movement and high-speed spin vibrations without placing stress on plastic connection ports.

• Durable EPDM Rubber Blend: Formulated to resist detergent corrosion, bleach degradation, high water temperatures, and continuous flexing.

• Smooth Inner Bore: Formulated to reduce lint accumulation, soap scum buildup, and air blockages.

Benefits

• Fixes Water Leaks: Resolves leaks occurring behind or under the washer tub during fill, wash, and spin cycles.

• Prevents Tub Pressure Build-Up: Allows displaced air to vent freely as water fills the wash drum, ensuring accurate water level sensing.

• Absorbs Spin Vibrations: Corrugated bellows expansion prevents hose detachment during heavy out-of-balance spin loads.

Applications

• Connecting the outer wash tub to the cabinet air vent assembly on compatible LG front-load washing machines.

• Replacing torn, cracked, leaking, or detergent-corroded internal vent hoses.
