Hi guys anyone know the size of the pipes which connect to the ace valve block, I have split pipe on the 4 pipe side and was looking to get some hydraulic fittings to repair or cut out the section and use flexi hydraulic hose, or is there a mod for fitting pipes,

Be aware that those pipes can run in excess of 50 bar of pressure...

thanks mikey, I will get some stainless hydraulic fitting with can withhold 1500 psi, 100 bar, I have tried to get the original pipes which fit to the manifold block, but not having much luck and not sure how they connect to the block, I can see 2x 13mm nuts which holds the flange to the valve but is this flange and the 4 pipes one unit or can you remove each pipe individually
