Right, I have a Serc oil cooler and was supplied aeroquip fittings to fit it. However they do not fit. Using my thread gauge, the comb that fits the serc thread says 7/16 or 14 (its a whitworth gauge). So I would now describe the thread as Whitworth 14 or BSP 7/16 thread. Is that right?
I cannot fathom using the gauge at all. Take -6 fitings, the catalogue says they are BSP 3/8 but my gauge measures the thread perfectly as 5/16.
I guess I wont get much feedback on this so while youre here, to put it another way, how do you connect a serc oil cooler with 7/16 thread and o/d 22.5mm fittings to -10 hose?
This is why people buy kits isn't it!:boohoo:
