These billet aluminium temperature adaptors fit in-line in an oil hose and allow either a mechanical or electrical sender to be installed. Our standard sender port is 3/8 BSP and can be used with the reducing bushes to allow for other threads to be installed. We list all common sizes, but if we do not have a size listed that is suitable for your application, please call or email and we will be happy to help you find the part you need.
