The TR414 Extended Rubber Tire Valve Stem​ is the industry-standard snap-in tubeless valve​ for wheels with deeper valve stem recesses. At 48.5mm total length​ (38mm effective stem height), it is slightly longer than the TR413, giving easier access for the inflator head and TPMS tool on thicker rims and certain hubcap designs—while fitting the same universal 11.5mm / 0.453" rim hole​ .Crafted from ozone-resistant EPDM rubber​ with a brass/zinc-alloy stem and high-temperature brass valve core, each TR414 is 100% leak-tested and pull-tested​ to exceed OEM requirements. The snap-in design installs directly into the rim without adhesives or special tools—simply lubricate the base, pull through the rim hole, and you're done.
