The Nissan TPMS sensors are made by Schrader Bridgeport so parts are commonly available. You don't need Nissan specific parts.
Most shops should have the service equipment and replacement seals nowadays considering TPMS sensors were made mandatory on all vehicles built since MY2008. IMHO, if the shop has no experience with TPMS systems DO NOT get your tires mounted there! They are easy to damaged if the tech is not properly trained on how to service them.
