Auto Spare Parts Radiator Iron Bracket OE 30723204 for Volvo S40 V50 C30 C70
The Left Lower Bumper Guard Rubber Seal (OE Number: 30744879) is a specialized protective and sealing component for specific SUV models (produced up to 2017). Installed along the left lower edge of the front bumper—typically at the junction of the bumper and front wheel well or lower body panel—it serves dual roles: shielding the bumper’s vulnerable lower edge from minor impacts (e.g., curbs, road debris) and creating a tight seal to block dust, water, and road spray from entering the bumper’s internal cavity.
This OE-grade rubber seal features a durability-optimized construction:
- Material: High-density EPDM (Ethylene Propylene Diene Monomer) rubber, chosen for its exceptional weather resistance (withstands -40°C to 120°C temperatures), UV stability (resists fading and cracking from sunlight), and resistance to road salt, oil, and chemicals. Unlike low-grade rubber seals (which harden or shrink over time), EPDM maintains flexibility and sealing performance for long-term use.
- Design: Precision-extruded to match the left lower bumper’s contour—its cross-sectional shape (often with a lip or bulb seal structure) and length align exactly with the target models’ bumper geometry. The seal includes integrated mounting clips or adhesive strips (per OE specifications) for secure attachment, ensuring it stays in place during driving vibrations or minor contact. Unlike generic seals, it eliminates gaps (which let debris accumulate inside the bumper) or misalignment (which causes wind noise), preserving the bumper’s factory functionality and appearance.
Core Functions
- Protect Bumper from Minor Damage: Acts as a shock-absorbing barrier for the bumper’s left lower edge, cushioning impacts with curbs, parking blocks, or small debris. This prevents scratches, dents, or paint chipping that would compromise the bumper’s structural integrity and aesthetics.
- Block Contaminants: Creates a water-tight and dust-tight seal between the bumper and adjacent body panels, preventing road spray, rainwater, dust, and dirt from entering the bumper’s internal cavity. This protects internal components (e.g., fog light wiring, bumper reinforcement bars) from corrosion and clogging.
- Reduce Wind Noise: The seamless fit and flexible rubber material minimize air turbulence along the lower bumper edge, reducing wind noise at high speeds and enhancing driving comfort.

*For 100% fitment accuracy:
- Confirm the vehicle’s bumper trim via VIN—base vs. sport variants may have slight differences in lower bumper design (e.g., added skid plates) that affect seal compatibility.
- Reference the vehicle’s official service manual to verify the seal’s exact mounting method (clip-on vs. adhesive) and installation sequence—incorrect attachment may cause the seal to peel off or lose its sealing effect.
- Note this is the left-side seal; do not interchange with right-side lower bumper guards—side-specific contour and mounting points will cause misfit and compromise protection/sealing.*

Frequently Asked Questions
Q: How to determine if the bumper bracket needs replacement?
A: Signs of a failing bumper bracket include visible damage or deformation, misaligned bumper panels, unusual noises from the front end, or if the bumper appears loose or sagging on one side.
Q: What should be paid attention to when replacing the bumper bracket?
A: For optimal results, we recommend professional installation. Key considerations include ensuring proper alignment of all mounting points, checking for additional damaged components, and verifying all fasteners are properly torqued to specification.
