LG Washing Machine Bellows

The LG Washing Machine Air Vent Bellows Hose (Part Number: 4738ER2001A) is an authentic original equipment manufacturer (OEM) replacement component designed for LG front-load and top-load washing machines. Positioned between the outer wash tub and the rear/upper cabinet ventilation channel, this flexible black rubber bellows vents air pressure and vapor during high-speed wash, rinse, and spin cycles. Its engineered accordion-style flex neck absorbs intense tub motion, preventing water splashes from escaping while ensuring smooth air displacement.

Key Features

• Corrugated Flexible Bellows Section: Engineered with an expandable accordion neck profile to absorb heavy tub vibration and movement without pulling loose or kinking.

• Moisture & Chemical-Resistant Rubber: Formed from high-grade elastomeric rubber designed to withstand continuous exposure to hot steam, detergents, fabric softeners, and humidity.

• Precision Sealed Flange Ends: Features molded retaining lips on both connection ports to ensure a watertight and airtight seal under spring or wire clamps.

Benefits

• Solves internal water leaks behind the wash tub, excessive sudsing issues, vapor leaks, or cracked air vent ducts.

• Protects internal electrical wiring and cabinet panels from moisture buildup and steam damage.

• Direct OEM replacement guarantees exact port sizing, length, and routing curvature.
