What's in the Box

If you have a power steering pump using late model style O-ring sealed hoses that you need to adapt to traditional inverted flare hoses, this inverted flare adapter is a simple fix. Simply insert the adapter into the flow control fitting and then install your inverted flare hose.

Use to convert from 16mm o-ring to 5/8" inverted flare style.

Works Good.

October 30, 2014
I had to put a different hydroboost brake unit in an 78 Gmc truck. I found a used one out of a 84 Chevy but didn't know they changed from flare fittings to o-ring fittings. Ordered these and they made everything hook up the way it should and it works good now. These are a little expensive though but was cheaper then having to make new hoses.
Pros:
  • WOrks good
Cons:
  • about $4 overpriced
Yes, I recommend this product.

Should it fit loose in the pressure fitting of the power steering pump? When I installed the adapter I was expecting a snug or interference fit in the fitting body. The adapter drops in and easily falls out is this normal? Does the small flange on the adapter make a tight enough seal after tightening the pressure hose nut that it will not leak? Thanks

This adapter is used to adapt an O-ring type pump to use an inverted flare hose. The round part of the adapter must seal on the O-ring in the pump and should have enough resistance to hold itself in place. If not then it will not seal and is more than likely not the correct adapter for your pump.

Can this be used in the steering box as well as the pump? I expect so as it should be the same concept but thought I'd better ask anyway. Thanks Gary

Yes it can be used in an o-ring steering box as well. It would have to be used in a 16mm o-ring seal port only. Most GM power steering boxes have two different thread sizes and this would only adapt one of the hose connections.

part # 91032921 This adapter is ONLY needed when you change the pump or pump flow valve fitting and your original lines are inverted flare. In that instance this adapter would go inside the O-ring style fitting and convert it to inverted flare to use with your existing lines. If your lines are already 5/8” or 16mm O-ring style the adapter should not be needed.

This adapter is designed to work with 16mm O-ring style when converting to 5/8” inverted flare. For use in other size fittings or steering gears or racks we suggest verifying available dimensions for an accurate fit. dimensions for this adaptor: O.D. .500" Height .404" The diameter at the base (where it fits in the flow-control valve, steering gear, or rack) .380"

If you have a power steering pump using late model style O-ring sealed hoses that you need to adapt to traditional inverted flare hoses, this inverted flare adapter is a simple fix. Simply insert the adapter into the flow control fitting and then install your inverted flare hose. Use to convert from 16mm o-ring to 5/8" inverted flare style. This adapter relies on the 45 degree taper on the inverted flare hose for secure seal and does NOT require an O-ring.

This is simply a flare adapter that works in conjunction with our flow valve 91032918. It converts the valve from O-ring style fittings to inverted flare style hose fittings. Our flow valve 91032918 is designed to work in the standard Saginaw style GM pump and some other applications and reduces the flow from 3 gallon per minute to 2 gallon per minute. The original valve is removed from the pump and the reduced flow valve installed in it’s place. It also works in the GM style remote reservoir pumps and the aluminum p/s pumps with or without reservoir. The valve will not fit most Ford and Mopar pumps. If desire to reduce flow on other styles of pumps we offer an adjustable flow valve under part number 91032923.

Part # 91032391 This adapter is designed to convert an O-ring style port to inverted flare hoses. It will not work in reverse. If you have an O-ring style hose end and need to install it in an inverted flare female on either the pump or the gear the easiest solution would be to have a local hydraulic hose shop change the ends on your line. Other option would be to change to a later pump or put AN6 fitting on your hose and an inverted flare to AN6 adapter in the pump.

Is this item marked wrong? Should it be for 3/8" inverted flare (3/8" inverted flare has 5/8" thread)? A previous answer says the fitting is 0.500" O.D. so how can it adapt to 5/8" flare? I have a GM Type II power steering pump and want to use 3/8" invert

Part # 91032921 This is simply the adapter to convert your original stepped O-ring female fitting on the pump or rack to inverted flare. It slides down inside the original female fitting and rests on the step where the O-ring would seal and changes it to Inverted Flare Female. Our website and also our catalogs have a photo of the part in question. If you want to run 3/8” hose (equivalent of AN6) you have a couple of options. This part and part number 6174802 will net AN6 male or part number 6174806 or 6174825 will net one fitting from the O-ring style to AN6. From that point on use the appropriate fitting to match your hose such as part number 6172040 to work in conjunction with the TFE hose such as part number 6173260. Clamp on hose is not recommended for high pressure power steering applications.

Mustang II Power Steering Flow Valve for GM Pump, 2 GPM
(Part #91032918)
                        

It is common to use an early GM power steering pump with a Mustang II power rack and pinion. Most who have tried it have found that the steering was twitchy or that it easily darts. This valve reduces the fluid flow from three gallons-per-minute to two gallons-per-minute, which cures the problem. For applications using the O-ring style power steering hoses. Installs in the back side of the pump as shown in the extra photos.

If converting pump from modern 16mm o-ring to traditional 5/8" inverted flare style hoses, order (1) Adapter Insert 910-32921.

Power Steering Hose Kit for 1982-88 T-Bird Steering Rack to GM Pump
(Part #91032535)
                        

Our standard power steering hose assemblies are an inexpensive alternative to the more costly stainless steel braided hose kits. This set adapts a 1982-1988 T-Bird/Cougar rack or our 91034340-POW rack to a GM style pump. Return hose will normally need to be cut to length.

The pressure line in this kit has an inverted flare fitting at the pump end along with a 14mm O-ring fitting on the rack end. It also comes with an adaptor so that it can work with an O-ring style (metric) pump fitting. We suggest using power steering pumps 91032922-GM or 910-32908.

Kit includes:

  • Adapter for the GM pump, to allow it to work with both metric O-ring and standard inverted flare style threads on the power steering pump fitting.
  • The fittings that go into the 1982-1988 T-bird rack which are 14mm O-ring (high pressure) and 16mm O-ring (low pressure return) with the smaller O-ring fitting hose end being the pressure side for the rack.

Mustang II-GM Pump Power Steering Hose Kits
(Part #91032530)
                        

It is common to use an early GM power steering pump with a Mustang II power rack and pinion. Our Mustang II/GM pump power steering hose assemblies are an inexpensive alternative to the more costly stainless steel braided hose kits. The return hose included in this kit will normally need to be cut to length.

This has an adapter to allow it to work with both metric O-ring and standard inverted flare threads on the power steering pump fitting.

This will work with the 1974-78 Mustang II power rack and pinion in conjunction with the suggested power steering pumps 910-32922-FORD and 910-32908-BLK. When using an early GM pump with Mustang II rack, you will also need flow reducer valve 910-32918. This valve reduces the fluid flow from three gallons-per-minute to two gallons-per-minute, which cures problems of twitchy steering when these components are used together.

Application:

  • 1974-1978 Must II Rack only
Heidts PS-101 Adjustable Power Steering Valve
(Part #91032923)
                        

If you have power steering on your car and it has too much assist or a 'twitchy' feel to it you may have too much pressure to the rack or box. 

This nifty valve allows you to adjust the pressure and get the road feel you want. It has a 1/4" npt inlet and outlet for the pressure line, and a 3/8" npt inlet and outlet for the return line. 

Both pressure and return line need to be plumbed into this valve.
