Aluminium One Eighth NPT Brake Line Lock Shut Off Valve Billet

Aluminium One Eighth NPT Brake Line Lock Shut Off Valve (Billet Aluminium) is an inline precision device designed to lock hydraulic brake lines, giving you controlled, momentary pressure retention when you need it most. Crafted from aerospace-grade 6061 aluminum and precision-machined to exact tolerances, this valve delivers reliable performance with a clean, anodized finish. Install it inline in your brake line system to hold pressure when the pedal is depressed, enabling deliberate, repeatable locking of either the front or rear brakes.

Designed for performance testing and track-style launches, this valve supports burnout capability, tyre warming, and grid starts by effectively holding brake pressure. Its robust construction handles high-pressure systems with confidence, rated up to 8000 PSI. The unit is compatible with Brake Fluids, Water, Fuel, Oil, and Air, making it versatile for a range of testing or race-day setups. Exact dimensions ensure a snug fit: Length 14.5 cm, Width 7.5 cm, Thread size 1/8" NPT, with back mounting threads M5 (4 of).

Every component is precision-machined to tight tolerances to ensure trouble-free performance in demanding environments. The hardware is finished with anodization for durability and corrosion resistance, delivering reliable operation under race-use conditions. This inline valve is intended for use in hydraulic brake line systems and is compatible with standard 1/8" NPT connections, making it a practical upgrade for track enthusiasts and serious DIY tuners alike.

All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
