This Forge one way valve has been designed specifically for vehicles that have supercharger or turbo conversions, with 13mm fittings. It is fitted in line, between the manifold and brake servo, to prevent positive boost pressure entering the brake servo. The brass billet piston and the aluminium billet body means it can withstand over 43 pounds per square inch.

This simple affordable solution ensures your brakes will always work and that your brake servo will not be damaged from excessive pressure.
