Lang Tools introduces the Rapid Tire Deflators with TPMS Location Marks, No. 401. The cut-out on the side of the socket allows for quick and easy deflation of tires. The back side of socket has a recess so when the tire is re-inflated, the socket can go on the cap to retain the TPMS location. Sockets are marked with TPMS locations (Right Front – RF, Left Front – LF, Right Rear – RR, Left Rear – LR). Bright anodizing makes sockets easily visible on most tires and rims. Patent pending. Made in USA.
