Bosch Wiper Blade Rear A381H, Length: 380mm – Rear Wiper Blade

Bosch Wiper Blade Rear A381H – 380 mm Flat‑Blade Design

The Bosch Wiper Blade Rear A381H is a high‑performance, flat‑blade wiper specifically engineered for rear windows of modern passenger cars and light commercial vehicles. Its 380 mm length provides optimal coverage on most standard rear glass panels, ensuring clear visibility during rain, snow or fog.

Key Features

• Flat‑Blade Geometry: The blade’s flat profile delivers even pressure across the entire width of the window, reducing streaks and improving wiping efficiency.
• Durable Rubber Compound: Made from a premium silicone‑based rubber that resists UV degradation, temperature extremes and chemical exposure. This guarantees long‑lasting performance in both hot summer climates and freezing winter conditions.
• Easy Installation: The A381H is designed for quick, tool‑free mounting on most rear wiper arms. Its secure attachment system prevents slippage during operation.
• Compatibility: Fits a wide range of vehicles including Mercedes‑Benz V‑Class, Opel Combo, Fiat Doblo, Land Rover Range Rover, Porsche Macan and many others that use the 380 mm rear wiper specification.
• Noise Reduction: The engineered rubber compound minimizes vibration and noise during wiping, providing a quieter driving experience.

Technical Specifications

Installation Guide

1. Prepare the Vehicle: Park on a flat surface, engage the parking brake and turn off the engine. Open the rear window fully.
2. Remove Old Blade: Locate the release latch or clip on the existing wiper arm. Gently lift the blade away from the arm, taking care not to damage the rubber edge.
3. Align New Blade: Hold the A381H by its edges and align it with the mounting points on the rear wiper arm. Ensure that the flat side faces outward toward the glass.
4. Secure Attachment: Press the blade firmly onto the arm until you hear a click or feel resistance indicating a secure fit. Verify that the blade sits evenly across the entire width of the window.
5. Test Wiping Action: Close the rear window and gently move it to simulate wind pressure. Observe the blade’s contact with the glass; there should be no gaps or uneven contact.

Performance Highlights

• Consistent Coverage: The flat‑blade design eliminates blind spots, especially at the edges of the rear window where conventional curved blades may leave streaks.
• Long‑Term Durability: Thanks to its high‑grade silicone rubber, the A381H resists cracking and hardening even after prolonged exposure to sunlight and road salts.
• Low Maintenance: The blade’s smooth surface is easy to clean with a damp cloth; no special chemicals are required.
• Enhanced Safety: Clear visibility from the rear improves driver awareness of traffic behind, reducing collision risk during lane changes or parking maneuvers.
