Chamfer on the Power Steering Fitting

[martsink]

Does anyone know the chamfer angle and size on the 986 power steering fitting? I need to make custom fitting for electric power steering conversion. I'm assuming its the same chamfer on both low and high pressure hoses?

I don't think the exact chamfer angle is critical - its usually machines on the shaft to help locate the shaft into the bore.
But if you need to know, just measure the outside shaft diameter & the internal chamfer diameter and work from there.

I assumed that the chamfer was the sealing face, like in the AN fittings. I worked out about 15 degrees using your method. If someone could confirm that the chamfer is just for locating and not sealing that would be great.

I think their price is ridiculous. I know its a low volume product, but I can't allow myself to spend $150 on two fittings (shipped). My friend said he can machine the fittings for free as long as I give him the drawings.

the gsr products don't look machined - they look like the ps fitting is welded to an AN fitting. buy some used ones on ebay and do the same thing (or take a saw to yours ...)?

I was thinking about it but the problem is that the stock fittings are non ferrous so they would be a ******************** to weld (possibly brass?). I don't know anyone who could do it. It looks like gsr did machine the Porsche fitting bit from steel and then just welded on a 6an fitting.

They are 2 fittings welded together. I purchased the Pump kit form GSR the beginning of last year it was on sale.
