Hello All, I am rebuilding my S1 and want to change the rusted bulkhead connectors. They are obsolete from Lotus.
Does anyone know what size / thread they are so I can find some alternatives / plated ones elsewhere? I assume they are a standard size.
Thanks
Simon
You mean for brake lines ? 10mm … If you feeling flush get stainless ones
Ok thanks, M10x1. (I binned the old ones which I had to cut off a long time ago).
I was thinking I need something like these
with a lock nut to clamp it against the “bulkhead”. This said, I think I’d better wait, before ordering, until my new Goodridge brake hoses arrive so I can check out the ends. In some images (most photos on websites are generic) it looks like the inboard end of these hoses have longer male connectors with a locknut which would go through the bulkhead. So I wouldn’t need another connector.
I’m being impatient wanting to order everything at once! ‘Procurement phase’ of project…easier than actually working on the car in the cold garage.
In that case waiting will mean you wont have 4 bulkhead fittings you dont need, the hoses do have a long male thread on them with locknut 
The only place I can remember a bulkhead fitting is from the front compartment into the cabin.
