Function
A wiper arm basically has to ensure that the wiper blade works with the correct pressure on the front and back windscreen. If the contact pressure is not sufficient, the wiper blade cannot clean the windscreen constantly and streak-free. The quality brand VAICO offers a wide range of wiper arms and wiper arm kits. The VAICO wiper arms are made of 70 % PBT and 30 % fibre glass ensuring a high longevity. Additionally, a special coating guarantees a high UV- and temperature resistance from -50 °C till 150 °C. Permanent and professional quality checks during the manufacturing processes ensure the VAICO wiper arms to be of high and long-lasting material quality.
