When customers look for a reliable supplier, product pictures and prices are not the only things that matter. They also want to understand how products are made and who is behind the manufacturing process.
At YARN, we believe that good products start with careful manufacturing and consistent attention to detail.
We specialize in diesel common rail fuel system components, including fuel metering valves, fuel pressure control valves, suction control valves, pressure relief valves and other related products.
Manufacturing a fuel system valve involves several steps. Each stage requires attention to product specifications, component accuracy and assembly requirements.
At YARN, our production team works with dedicated equipment and established manufacturing procedures to maintain product consistency.
From individual components to finished products, every step is part of the manufacturing process.

YARN's production team is led by over 20 year experience engineer, who has extensive technical experience in automotive parts.
His practical experience helps connect product requirements with manufacturing and quality control.
We also use equipment from Japan and Germany in our production process.
