Required for use in some brake conversions. 3/8”-24 inverted flare removable fittings. Residual valves are used to maintain constant pressure on the brake system. For drum brakes, a 10 lb. residual valve is used to hold pressure against the springs in the drum. This allows the drum brake to engage more quickly and reduces pedal travel. For an under-the-floor master cylinder brake system, a 2 lb. residual valve is used for disc brakes to keep brake fluid from flowing back down into the master cylinder.

product looks well built. Only issue is there are no markings on it that indicate which direction to mount it. Made three calls to tech support. Called FL, NC, and MI and each person couldn't tell me how to install it. One person told me it was a proportioning valve and said it didn't matter which direction it goes in. After asking on a mustang forum i eventually got my answer. The side with the flat relief should be up stream. I would recommend this product but I would hope NPD has better instructions and knowledge about this product with their tech support.

Screwed right in, doesn't leak, holds pressure. Does exactly what you want a residual valve to do.
