Wiper Blade Bosch Twin 420U

Description

Bosch Twin 420U – wiper blade is 425 mm long and incorporates a frame assembly.
420U – an all-weather wiper blade built to handle rain, sleet, snow, and heat with consistent, long-lasting performance.

The replacement blade showcases a durable alloy structure with multi-pivot joints, crafted to provide even pressure distribution on complex windshield shapes. The high-grade polymer wiping edge is firmly anchored in a U-channel, delivering a tight seal across the arc. Easy-to-replace refills and multi-vehicle fitment make it a budget-friendly solution for older models. It delivers a durable galvanized frame that resists corrosion and mechanical wear, a multi-pivot action that adapts to complex windshield curves and a simple rubber refill system that extends service life while reducing total cost of ownership. However, exposed hinges may freeze and clog with dirt during winter, at high speeds it can experience wind lift and increased noise, and natural rubber wears faster in sunlight whereas polymer composites command a higher price. Periodically clean and lubricate the hinges with a silicone spray every three to six months and replace the wiping edge every six to twelve months (or every four to six months in harsh climates). Perfect for mild weather, daily commuting and economical drivers, this blade ensures dependable performance, clear visibility and lasting value at an affordable price.
