For those who want to use other stuff than seastar product, there is another possibility:
If you are ready to change the sea star for industrial hose rated at the same or far above the sea seastar pro, you can buy a straight fitting for your ram at the size 1/4NPT MALE/JIC 05
Then ordered a hose with a female JIC 05 stainless steel on the ram side, and regular steel on the pump side.
The seastar pump use also the same fitting , but you can order a 90° if you want.
1/4NPT MALE/JIC 05 90°
I did the same operation for a friend last year, and it's absolutly trouble free.
After this in case of need to change the lenght of hoses just go to the hydraulic shop next to your city.
Here a good brand in France:
