Washer on front brake line connection to Master cylinder

Hi can anyone tell me if there is a copper or fibre washer where the stainless brake line enters the master cylinder It does not show one in the parts book but it seems to me that there should be a washer similar to the brake switch Thx Drummer99

The original line wasn't stainless so it depends which fitting this aftermarket stainless line has as the master cylinder has an internal tapered seating but is probably too deep for the majority of brake line fittings to reach (the original 'rubber' line end fitting is also too short to seat against the taper) so a (preferably) copper or aluminium (definitely not fibre) sealing washer will almost certainly be required.

Just did one with ss line. Copper washer and a dab of permatex thread sealer.
