{"product_id":"wilwood-260-8419","title":"Wilwood Knob Brake Proportioning Valve with 3\/16-inch Line Adapters, NPT Ports","description":"\u003cp\u003eThis knob-operated proportioning valve changes the rear circuit pressure relationship to help balance a custom brake system. Its NPT body ports are supplied with two 3\/8-24 inverted-flare adapters for 3\/16-inch double-flared hard lines. Bill Wood's founding of Wilwood Engineering in 1977 established a disc brake design and manufacturing business based in Camarillo, California. Calipers, rotors, master cylinders, fittings, valves and brake lines form its range for motorsport, street-performance and specialized applications. Choosing a service component still requires checking the mating parts and overall system configuration.\u003c\/p\u003e\u003ch3\u003eTechnical Details\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer part number:\u003c\/strong\u003e 260-8419\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Aluminum \/ Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish:\u003c\/strong\u003e Clear Anodize\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum pressure reduction:\u003c\/strong\u003e 57%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting:\u003c\/strong\u003e Two 0.25-inch holes on 1.00-inch centers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUse:\u003c\/strong\u003e Custom brake-system proportioning, normally in the rear circuit; not a direct OEM replacement\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure connections:\u003c\/strong\u003e Native 1\/8-27 NPT inlet and outlet; two 3\/8-24 female inverted-flare adapters supplied\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustment:\u003c\/strong\u003e Rotary knob\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment \u0026amp; Compatibility\u003c\/h3\u003e\u003cp\u003eInstall in the appropriate rear pressure circuit with flow following the IN and OUT markings.
