It uses a 1/2-inch inner diameter rubber hose with 3/8-inch NPT end fittings—one fixed and one swivel—to allow installation without twisting the hose. Typically replaced when the flexible section shows cracking, leaking, or wear, or as part of scheduled brake system maintenance. The hose meets DOT FMVSS No. 106 and SAE J1402 Type A standards for safe, reliable performance.
