This stainless steel Tee fitting has two reusable 3AN hose ends built into the two "run" sides and a female 1/8 NPT fitting on the branch. It makes it easy to install a brake light switch or brake pressure sensor in your -3 brake line without adding two additional hose ends. It can also be installed in a -3 oil pressure gauge line to add a low oil pressure warning light switch.
Does not include switch or sensor.
