Question by: Freddie F on Mar 24, 2025, 6:57 PM

does this fitting work with -12 hose on a 4-wire spiral assembly, or do i need a different dash size?

Answer by: Customer Support on Mar 26, 2025, 1:55 PM

the -12 hose dash size is exactly what this fitting is built for. It pairs with 4-wire spiral hose and uses an ORS end on one side with a line/hose/tube end on the other, so you've got a female ORS connection going into your port and the hose end taking care of the other side. Just make sure your existing assembly matches that configuration before ordering.
