Both types serve to seal around the valve stem hole in the rim and house the valve stem core, which holds pressure in the air space inside the tire/rim assembly. Press-in stems are rubber assemblies that are held in place by the interference fit between the stem and the rim hole. Screw-in stems are threaded metal assemblies with a rubber seal on the inside of the rim and a locknut that clamps the stem in place and compresses the inner seal against the inside of the rim. Both types are easily replaced with a minimum of specialty tools and training. Insert the valve stem tool into the valve stem and engage it in the notches in the valve core.
