does anyone have a 5/8 BSP tap and Die they can lead me?

5/8 BSP? Are you sure??

yea, its not for a kit car, its for a Range Rover Powersteering box.

bit over enthusiastic with the worlds second most useful tool, and we "ovalled" a fluid feed...

I have a 5/8 bsw which i assume is whitworth?
Is the thread pitch different?

I'm not an expert in anything but I've never heard of a 5/8" pipe. Can you check the dims and TPI with a Zeus book and see what else you get??

ok.

to remove the fitting, we used a 16mm spanner.... the thread on the male fitting wass only just smaller than the bit where the spanner fitted. I called RVC in tonbridge ( Land Rover specialist ) who said he did not know what it was, but knew it was a BSP thread. I then called up HA HA hydralics in Maidstone who did not know what it was, but gave me the sizes it could be...

1/2, 5/8, 3/4.

0.5 * 24 = 12mm - too small.

5/8 * 24 = 15mm - almost perfect.

3/4 * 24 = 18mm - way too big.

so im guessing its a 5/8 BSP thread.

its a big hydralic line - not a brake line.

Nearest BSP sizes are:
O/D of 1/4 BSP = 13.16mm
O/D of 3/8 BSP = 16.6mm

BSP sizes use the bore of the pipe as the nominal size, not the O/D (outside diameter)

Also, inches to mm is 25.4, not 24

HTH

so its more than likely to be 1/4 bsp?
