Hi guys,
I just thought I would share an experience with you all- this is not an attempt to slander anybody, just some observations I have made that I feel may of benefit to others.
My best mate and I are upgrading the turbo on his project car and obviously needed new oil/water lines and fittings. Despite the fact that no expense has been spared on the car, we opted for the cheaper 'ProFlow' fittings, over the more expensive 'SpeedFlow' fittings.
In the end, the saving was false- the quality of the 'ProFlow' fittings did not seem to be as good as the 'SpeedFlow' ones- the barb on the fittings do not sit securely inside the hose, and when tightening the locking collar, the hose would sometimes get pushed out the bottom. The braided line also seemed to fray badly, which hampered our efforts slightly. It must be stated for the record that neither of us are mechanics, but we have some reasonable experience and the ProFlow fittings were considerably more difficult to use than the SpeedFlow fittings we have used in the past. Their customer service experience was also not the best in dealing with issues/complaints.
If you do decide to buy ProFlow fittings, ensure that you buy the correct fittings for the line. The '200' series hose ends will only fit '200' series hose and so on. (Common sense but confusing from their web-site.)
End of the day, if you are tossing up between the two fittings, I would suggest SpeedFlow!
As a side note, we have to thank Tim from Pirtek at Asquith for his help and high quality of customer service.
