Proportioning Valve Fitting Kit

The LEED Brakes Proportioning Valve Fitting Kit (Model FKPV) is a precision hydraulic adapter set engineered for brake system installations where multiple fitting sizes must interface with a single proportioning valve. This kit assembles the four male fitting sizes—3/8 inch, 7/16 inch, 9/16 inch, and 1/2 inch—required to adapt different brake line diameters to standard proportioning valve ports, eliminating the need for separate component purchases or custom machining during system fabrication.

Proportioning valves regulate brake pressure distribution between front and rear circuits to prevent rear-wheel lockup during hard braking. The kit's zinc-finished brass fittings provide corrosion resistance in both dry shop environments and salt-exposed conditions common to marine or coastal duty. Each fitting is manufactured to SAE thread specifications, ensuring leak-free seals when properly installed with standard brake system flare nut wrenches. The compact kit packaging—measuring 3.05 x 2.05 x 0.75 inches and weighing just 0.11 lbs—stores easily in toolboxes or mobile maintenance units.

This fitting kit addresses a common hydraulic brake assembly challenge: sourcing compatible adapters when integrating aftermarket proportioning valves into vehicles with mixed brake line sizes. Technicians restoring classic vehicles, fabricating off-road brake systems, or upgrading towing-equipped trucks benefit from having all four essential sizes in one assembly. The proportioning valve fitting kit reduces downtime from hunting individual adapters and ensures pressure regulation consistency across varied line configurations.

LEED Brakes maintains a reputation for precision brake component manufacturing, with products commonly specified in hot rod, restoration, and heavy-duty suspension shops. The FKPV kit integrates into systems using LEED proportioning valves or any proportioning valve with standard SAE ports, making it a universal compatibility solution for brake builders and technicians.
