Anyone know the size and thread pitch for the power steering pressure hose fittings?

The relatively new power steering pressure hose on my ‘88 GTA just sprung a leak. Rather than buy another cheap OEM type hose from Pep Boys I want to buy/make a braided hose.

From what I have gathered I need an 18mm to –6 O-ring adapter for the steering box, a 16mm to –6 O-ring adapter for the pump and of course the appropriate braided hose and –6 fittings.

Can anyone confirm these fitting sizes?

Thanks.

 

just take you old lines with you to the shop and tell them to make you a line with these ends on them, or adapters to make them work.

 

They are unique. No common fittings that I know of are like them.

Buy the right hose. Then if you really want a braided stainless one, use the pieces of correctly bent tubing that are part of it, and just replace the rubber piece with braided line. I seriously doubt you could make a whole one out of flex line, and not have it flopping around and getting into the exhaust and otherwise not fitting the car worth a flip.

 

Thanks for the input guys. I am going to hit my local Aeroquip hose supplier today and ask about having a line fabbed up. I'd prefer not to use the factory fittings, but if that's the only way I can get it done then that's the route I'll go. I've had them do this with brake lines in the past.

FYI - I found several race shops online that offer complete power steering hose kits for "1982 and Up GM Power Steering". They list the adapter fittings available as:
-6 18mm Large Fitting
-6 14mm Medium Fitting
-6 16mm Small Fitting

And yes, I have the specs right. How a 14mm fitting gets listed as "medium" while a 16mm gets listed as "small" I'm not sure. That's why I wanted to see of anyone could confirm the fitting sizes.

Thanks again. I'll post my results from the hose shop.

 

Okay, I'm all squared away. I dropped off my old factory original hose at a local Aeroquip supplier and they are going to cut off the crimp connections and braze on threaded fittings to the tubes. From there, they'll fab up some blue braided hp hose with reuseable fittings. All for around $40.

From now on if I ever blow the hose (very unlikely) all I'd have to do is pick up some new hp hose and reassemble the line.
