Sankei

About Sankei Industry Co., Ltd.

Sankei Industry Co., Ltd., widely recognized through its iconic 555 (Triple Five) brand mark, is a Japanese automotive aftermarket parts manufacturer with a legacy stretching back to its founding in Ritto, Shiga Prefecture in 1960. Over more than six decades, the company has grown from a domestic supplier into a globally trusted name, with its parts now sold as critical safety and performance components in over 120 countries worldwide.

Sankei's core philosophy has always centered on precision engineering and uncompromising quality. Sankei parts are designed using CAD software and subjected to rigorous testing protocols to ensure they perform reliably across a wide range of real-world conditions — from daily urban commutes to demanding off-road and extreme-climate environments. The company's manufacturing process involves carefully selected materials, advanced automated machinery, and multi-stage quality assurance procedures aimed at eliminating defects at every stage of production.

In August 1999, Sankei received ISO 9001 certification for its quality management systems — a milestone that underscored its commitment not just to product quality, but to continuous operational improvement across all aspects of the business. With a product line of more than 2,000 items covering vehicles from compact light cars to heavy trucks, Sankei offers one of the broadest catalogs of Japan-made replacement parts available on the global aftermarket.

One of the brand's distinguishing strengths is its coverage of older and discontinued vehicle models. While many manufacturers focus exclusively on late-model applications, Sankei has long maintained catalog entries for legacy platforms — making it an especially valuable resource for owners of classic or hard-to-source Japanese vehicles.

Sankei's sensor and switch lineup complements its broader parts offering, providing drivers with reliable engine monitoring components. Whether you need an Engine Cooling Fan Switch to protect your engine from overheating, an Engine Oil Pressure Sensor for accurate instrument panel readouts, an Engine Oil Pressure Sender With Gauge for legacy gauge-equipped vehicles, or an Engine Oil Pressure Switch to trigger warning indicators, Sankei's Japan-made components are engineered to OE-matching tolerances. The brand also offers PCV Valves to help maintain proper crankcase ventilation and engine health.
