{"product_id":"wilwood-130-4346","title":"Wilwood Four-Pack Caliper Square Piston Seals, 1.620-Inch Inside Diameter","description":"\u003cp\u003eThis four-piece square-ring kit uses the listed 1.620-inch inside diameter and 0.099-inch section. It is a defined piston-seal service pack and should be distinguished from six-piece or dust-seal combination sets using similar size labels. The exact caliper parts listing identifies where these rings belong. Wilwood Engineering was founded by Bill Wood in 1977 and is based in Camarillo, California. The company makes disc brake systems and components for motorsport, street-performance and specialized uses, including calipers, brake rotors, master cylinders, valves, fittings and brake lines; each component must match the requirements of the complete brake system.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eManufacturer part number: 130-4346\u003c\/li\u003e\n\u003cli\u003eService component: Caliper Square Ring Kit\u003c\/li\u003e\n\u003cli\u003eSeal profile: Square-Ring\u003c\/li\u003e\n\u003cli\u003eManufacturer-listed seal inside diameters: 1.620 inches\u003c\/li\u003e\n\u003cli\u003eListed seal thickness: 0.099 inch\u003c\/li\u003e\n\u003cli\u003eManufacturer material code: 210M\u003c\/li\u003e\n\u003cli\u003ePack quantity: 4 Pack\u003c\/li\u003e\n\u003cli\u003eSeal fluid compatibility: DOT 3, DOT 4 and DOT 5 as specified for these seals.
