Hydraulic steering problem

[largecar91]

I am rigging my new boat and have a seastar pro helm and cylinder. I am running it thru a ultraflex bulkhead fitting. The threads appear to be 9/16 24. I want to run braided stainless to steering cylinder. Does someone make a fitting to adapt to an AN fitting.

I have never tried to change fittings. but they do make a flexible rubber boot, just made for steer hoses to go through deck.

Thanks. The I don't care for the rubber boot and I already have the thru hull fitting and is anodized red to match so I am pretty much stuck trying to make what I have work. Seastar makes a pro hose in short lengths which is how I will probably have to go unless I can find fittings to convert it to AN

Is this what you are saying you have, the plate being red? http://www.ultraflexgroup.com/easyUp/store/Zoom/827_r9b_09_psll_z.jpg

The plate is the same one. The fitting would be great if it is the correct size threads on the female end. I just got off the phone with a Seastar tech and he told me there are no fittings to adapt this to an AN(???). He said it is a 9/16-24 ultra fine thread. I would sure this someone has a fitting.

Take it to your local hydraulics shop that builds hoses like a Parker distributors hose shop for example.

They should be able to hook you up. It might take two fittings though but I doubt it. The fitting has to be out there somewhere.

He's pullin your leg, seastar didnt invent the thread size, been a couple years since i did it, but i run shop made hoses 5000psi on my allison, i would have to find the sizes again.

Earls does offer this fitting as a 14mm x 1.5 thread female to -6 male AN. 14mm equals 9/16''. Thread count comparable? I believe 1.5mm threads would be 16 threads per inch(TPI) not 24. Not sure.

Yessir metric threads come in 1.25 ,1.5 and 1.75 generally, 1.25 being very fine

We make horses at my shop. The parker salesman was there yesterday. He said he had nothing to change it over. My last boat had non pro seastar. My shop made hoses for it.

BrassCraft has the adapter fitting you are looking for. Its their part F10-6. Go to their site to be sure. Send them to the chrome shop. https://www.coburns.com/resize?po=http%3A%2F%2Flibrary.coburns.com%2FImages%2FIMAGE_Brasscraft_F10-6.jpg&bh=250

The thru Hull uses a 3/8” compression fitting, it’s not NPT so unless the large side of that brass fitting is identical to the fitting end on your Seastar hose (and it isn’t because that fitting does not exist) then that will never seal properly and do you really want a leaky steering system?

The connector end needs to look like this to seal on that fitting. https://goo.gl/images/yhKLxJ

The only real solution you have is the ditch the UFlex thru Hull and use a Seastar thru Hull which will give you the NPT thread you will need on the cylinder side along with the proper hose fitting on the inside.

the seastar hose ends are not NPT they are whats called 3/8 TUBE its basically not tapered like an NPT is....I dont know the thread pitch off hand... i have found random fittings for them at times but its not easy usually whatever i find is brass not stainless.....that 9/16 ultra fine thread the seastar rep mentioned sounds like what they use on there new ORB fittings not the older style stuff we are all used to...Seastar doesnt like anyone messing with there stuff so they give as little info that they dont think you should have as possible....

Steering systems used to be so easy



just saying

Wait you know steering stuff?? I thought your specialty was just garden hoses??? Lmaooo....

Billy alot of stuff is more comolicated now....remeber when cars and outboards just had simple carbeurators....

Not sure if you are referencing my comment on NPT or not. The NPT I’m referencing is the Seastar thru Hull bulkhead fitting, not the hose end. Seastar uses a brass NPT tube and NPT to 3/8” compression fittings for the hose connections with their thru Hull kit. If you absolutely must have stainless braided line with AN fittings on the motor side you can leverage that part to get there.

Just referencing this whole thread and saying that seastar is a pain in th arse...lol...when the whole hydraulic steering world used to use an fittings they came along bought alk the steering companies killed them off and complicated things...

403342403343Been a few years since this was done,I would have to take fitting into a shop and find out the size,but it ain't no seastar fitting,and it had no issues threading in.

[ghost28]

No the sastar rams are NPT so you can convrt th ram to -4 -6 etc and you can mke your own hoses....but if you wanna use seastar hoses you ned to use he 3/8 tube fittings for there hose ends to fit

Just to make things even more confusing all the new Seastar rams and helms are ORB fittings, not NPT but that’s fine because there are tons of ORB to AN fittings available.

[ghost28]

And the orb fittings are very finiky...the small jam nut likes to crack and yhen they leak....

[FUJIMO]

If at all possible, I don't know...and if I was starting from scratch, with a UltraFlex helm thingy...I would adapt the helm to accept conventional AN(army-navy) hose & fittings. Then no worries from there back...ever. Thats just me.

Thanks guys very much for the info.
