Hi,
I have added two rear remotes to my tractor, to easily operate them I am swapping my two spool valve to a four spool. The inlets and outlets are close together and each pair are directly behind one another. On my existing two spool valve I used 90s in a fan shape and had enough room to get everything out but with twice as many lines I do not have the room. Ideally I need an 8 ipM to 8 IP 90 thats about 3.5 inches high to put on the back lines elevating them overtop of the front lines. But I dont seem to find anything close. I can not go with just the rubber hoses as they would be bent at sharp angles and they would catch tree branches .
What has anyone else done to make a neat compact connection?
thanks

If you put JIC males on adaptors that go into the valve body, you can use JIC 90s and straight hose ends instead of 90 degree hose ends. The JIC 90s come in different lengths or you can use straight JIC extenders

Also, it'll help you to know that both the JIC and SAE elbows come in standard, long (L) and "long long" (LL at the end of part #) -

if you have all valve ports on the same level and you want them to exit at 90* in an "over/under" pair, you need a regular and a LL - a short and a long will NOT be enough height difference... Steve

Thanks Leejohn, I'd forgotten the extra option for pipe/JIC's
