Mayb e this one?@Vivid Creative Aquatics marinedepot sells the reducer bushing,so i will go that route. Unfortunately that pvcfittingsonline their shipping is expensive. Its $5 w/ shipping @ MD,$9.35 @ PVCFO.
I got the 1/4" adapter with my order,so I gonna order the bushing here shortly. Too bad I can't find a 1/4" bulkhead..
not a lot of details on it, but it might work as a bulkhead.
IMO - If you have the room, the 1/2in Bulkhead I think is the better way to go. it affords more flexibility should you ever what to change things up
