These Camozzi Bulkhead unions are helpful when running hardlines into the floor and then softlines underneath. Drill a hole in the surface you want to pass through, and use the included nuts to affix the union through the hole. PTC connections on either side make plugging and unblugging lines a breeze. These fittings are DOT approved, and the silver finish on them might match your finished trunk setup better than the brass SMC DOT Bulkheads.
DOT approved We do not recommend using stainless steel hardlines with PTC fittings
