Thread: Brake system

Tweet

All, according to the tech guys "These straight thread, 90 degree fittings only require the O-Ring washer to orientate the -4 AN fitting into the angle alignment desired." I take that to mean you do not need to seat them and can position them in any direction you need to accomodate your situation. Am I off base here?

ps: I have also ground the fitting on the end, if it did not seat in the proper position. I felt better having a matting surface (contact on the inner flare). They do build quit a bit of pressure if you have to stand on the brakes.

yes that is the way i see it. the amount of psi and no receiver for the o ring with a strait theads with no seat for the fitting to seat up to .you are using the o ring and not the way it was made to work .i would want more than that for a brake system
