This is a NEW Low-profile Metal Shorty TPMS Valve. This valve is (30.0 mm) from inside grommet to cap making it less than 1" once mounted sticking out of the wheel. This is the short metal version of the 20018 valve. This valve is perfect for solving tricky clearance issues, large calipers, control arm etc. Anything that a stander size valve would be in the way.
NOTE: TPMS Valve Stem base is not threaded. Each valve comes with a self-tapping screw.
