Technical Specifications:

• Inner Diameter (Drum Side): 470mm
• Outer Diameter (Door Frame Side): 510mm
• Fold Count: 3-fold bellows design
• Material: EPDM (Ethylene Propylene Diene Monomer) rubber
• Temperature Range: -30°C to +135°C
• Color: Grey with optional anti-mold additive

Functional Features:

• Triple-lip seal design for enhanced leak prevention
• Anti-microbial treatment embedded in rubber compound
• Flexible fold geometry accommodates door swing and drum expansion
• Self-cleaning groove on inner lip to prevent debris buildup

Performance Parameters:

• Compression Set: ≤ 25% after 70 hours at 70°C (ISO 815)
• Tensile Strength: ≥ 12 MPa (ISO 37)
• Elongation at Break: ≥ 350%
• Water Pressure Resistance: Tested to 2 bar sustained pressure without leakage
• Service Life: ≥ 5 years under normal household use

Material Composition:

• Primary Compound: EPDM rubber with carbon black filler
• Reinforcement: Internal fabric mesh (polyester) for tear resistance
• Anti-Mold Additive: Zinc pyrithione-based biocide
• Color Pigment: Iron oxide grey

Structural Features:

• Circular ring with 3 symmetrical folds creating accordion-style flexibility
• Reinforced bead on drum-contact edge for wear resistance
• Magnetic strip channel (optional) for AEG door interlock alignment
• Smooth outer surface for easy cleaning

Working Principle:
The bellows compresses against the drum opening when the door is closed, creating a dynamic seal that flexes as the drum rotates. The triple-lip configuration provides redundant sealing — even if the primary lip experiences minor wear, the secondary and tertiary lips maintain water containment. The accordion folds allow axial movement of up to 15mm to accommodate drum vibration.

Key Advantages:

• Superior leak protection at high spin speeds (up to 1600 RPM)
• Anti-mold formulation prevents odor and discoloration
• Extended service life with reinforced fabric mesh
• OEM-exact fitment for AEG front-loader models

Applicable Industries:

• Washing machine manufacturing
• Appliance spare parts distribution
• Professional appliance repair services

Installation Requirements:

• Seat bellows into door frame groove using a thin film of silicone lubricant
• Ensure no twists or pinches in the fold section
• Verify full 360° seating before closing door
• Check that door interlock magnet aligns with sensor position

Usage Precautions:

• Clean folds regularly to prevent detergent residue buildup
• Do not use petroleum-based cleaners — use mild soap and water only
• Replace immediately if cracks, hardening, or permanent deformation is observed
• Store spare bellows in cool, dark location away from UV light
