It is a mixed-size hydraulic service pack with the 0.099-inch square section.

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: 130-9173\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: 1.880 \/ 1.620 \/ 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: 6 Pack\u003c\/li\u003e\n\u003cli\u003eSeal fluid compatibility: DOT 3, DOT 4 and DOT 5 as specified for these seals.
